An exponent of a number appears how many times we are multiplying a number by itself. For example, 3³ means we are multiplying 3 four times. Its expanded form is 3×3×3. An exponent is defined as the power of a number.
The exponent of a number defines how many times the number is multiplied by itself. For example, 2×2×2 can be written as 2³, as 2 is multiplied by itself three times. Here, 2 is said to be the "base" and 3 is said to be the "exponent" or "power." In general, [tex]x^{n}[/tex] this means that x is multiplied by itself by n times.
Example : 5*5 = 5²
An expression that means repeated multiplication of the same factor is called a power.
The number 5 is said to the base and the number 2 is said to the exponent.

How many images are formed If two plane mirror are position at an angle of 450?
There are seven images are formed If two plane mirrors are positioned at an angle of 45°.
The formula for the number of images formed by two plane mirrors placed at a certain angle is
⇒360/n
where n=angle between the mirrors
The most important thing to remember is that every time the number of images formed is only ODD numbers, if the result is even then you need to subtract 1 from that.
if it is odd u need not subtract, since the number of images ever formed is only odd.
so for an angle, of 45° the number of images formed are:
⇒360/45=8
in this case, since the images formed are even u need to subtract 1 from it i.e
8–1=7
So, the number of images formed is 7.

Answer: i believe is c or d i not 100% sure
A alone can do piece of work in 6 day and B alone in 8 day. A and B undertook to do it for $3200. With the help of C, they completed the work in 3 day. How much i to be paid to C?
If A alone can do a piece of work in 6 days and B alone in 8 days, then A and B undertook to do it for $3200 and complete the work in 3 days with the help of C, then C would be paid 400 dollars.
Therefore the answer is $400.
This is a work and time problem that can be solved using the concept of rate of work. Let's call the amount to be paid to C as "x".
A can do 1 piece of work in 6 days. Therefore, his rate of work is 1/6.
B can do 1 piece of work in 8 days. Therefore, his rate of work is 1/8.
Amount of work A and B can do in 3 days is
= 3×(1/6) + 3×(1/8)
= 3×(1/6)×(4/4) + 3×(1/8)×(3/3)
= 12/24 + 9/24
= 21/24
= 7/8
So amount of work C doing is
= 1 - 7/8
= 1/8
As C do 1/8 amount of work, the amount C would receive is
= 3200 × (1/8)
= 400

The function a(g)=10-log base 3(g+1) represents the home attendance of a football team in hundreds depending on the number of home games, g.
How many people will attend the second home game?
How many people will attend the eighth home game?
At which game were there 500 attendees? Does this answer seem reasonable based on context of the problem?
The number of people that will attend each game is given as follows:
Second game: 9,000.Either game: 8,000.The number of attendees will be of 500 on the 857th game, which does not make sense in the context of this problem, as a football team plays at most nine home games during a season. (taking the NFL in context).
What is the logarithmic function?The logarithmic function for this problem is defined as follows:
[tex]a(g) = 10 - \log_3{(g + 1)}[/tex]
Hence the number of people that will attend the second home game, when g = 2, is given as follows:
[tex]a(2) = 10 - \log_3{(2 + 1)}[/tex]
a(2) = 10 - 1
a(2) = 9.
Hence 9,000 people, as a(g) is measured in thousands.
The number of people that will attend the eight home game is given as follows:
[tex]a(8) = 10 - \log_3{(8 + 1)}[/tex]
a(8) = 10 - 2
a(8) = 8. (8,000, considering the unit of a(g)).
The game in which 500 people will attend is obtained as follows:
[tex]0.5 = 10 - \log_3{(g + 1)}[/tex]
[tex]\log_3{(g + 1)} = 9.5[/tex]
Applying the cube to both sides, we have that:
g + 1 = 9.5³
g = 857.

What is VAT?VAT meaning value added tax that is attached to an item of product while bought by the buyer and also in each stage of production, distribution level. It is almost similar to a sales tax that is paid within the item price.
What is the value of discount?
given, discount allowed = 20% on the market price.
VAT = 10% on the market price.
Buyer paid as VAT = 320 Rs
Assume, market price of radio = X Rs
now amount of discount = 20/100× X = 0.2X
amount of VAT = 10/100×X = 0.1X
it is said that VAT paid by buyer = 320 Rs

Simon's photo album has 8 photos of his car and some photos of his motorbike
He replaced some of the photos of his motorbike with some more photos of his car.
The number of photos of his car became 12. The ratio of the number of photos of his car to his motorbike became 3:5. How many photos of Simon's bike was there in the album ORGINALLY?
There were 24 photos of Simon's motorbike in the album originally.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Let x be the number of photos of Simon's motorbike in the album originally.
We know that the number of photos of his car became 12, so the number of photos of his car originally was 8.
We also know that the ratio of the number of photos of his car to his motorbike became 3:5.
So the number of photos of his car and his motorbike originally was x-4.
We can set up the following equation:
12/(x-4) = 3:5
We can cross-multiply and simplify to get:
3x - 12 = 60
3x = 60 + 12
3x = 72
x = 72/3
x = 24
