Change of base formula is used to rewrite a logarithmic operation as a ratio of two logarithms each with the same base that is different from the base of the original logarithm, for example, log₆₄8 = log 8 / log 64.
Logarithm is the inverse function of an exponential. The logarithm of x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
Change of base formula is used to rewrite a logarithmic operation as a ratio of two logarithms each with the same base that is different from the base of the original logarithm. It can be written as follow:
[tex]Log_{b} a = \frac{Log_{d} a}{Log_{d} b}[/tex]
For example:
We want to find the value of log₆₄8 using the change of base formula.
log₆₄8 = log 8 / log 64
= log 8 / log 8²
= log 8 / 2 log 8
= 1/2
Thus the log₆₄8 is 1/2

Combine like terms
7k + 4(k + 4)
A.8k + 16
B.11k + 16
C.7k + 1k + 16
D.27k
Answer:
B. 11k + 16
Step-by-step explanation:
We have an expression and are asked to combine like terms.
To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.
(4(k) + 4(4))
4k + 16
7k + 4k + 16.
Since 7k and 4k are like terms since they end in the same variable, we can only add them.

An algebraic expression is given. Use the expression to answer the following questions,
a) How many terms are there in the algebraic expression?
b) What is the numerical coefficient of the first term?
c) What is the constant term?
d) Does the algebraic expression contain like terms? If so, what are the like terms?
X+ 3+ 7x
The
Answer:
A. 2
B.1
C.3
D. (should be x and 7x but that isnt an answer choice so) no
Step-by-step explanation:
For given expression x + 3 + 7x,
a) the number of terms in an algebraic expression = 2
b) the numerical coefficient of the first term = 1
c) the constant term = 3
d) the like terms are x and 7x
What is an algebraic expression?"It is a mathematical expression that consists of variables, numbers and operations."
What is constant?"It is a value or number that never changes in expression."
What are like terms?"The like terms are defined as the terms that contain the same variable which is raised to the same power."
For given example,
We have been given an expression x + 3 + 7x
a) x + 3 + 7x = 3 + (1 + 7)x
= 3 + 8x
So, the number of terms in the algebraic expression = 2
b) for given expression x + 3 + 7x,
the first term is x
x = (1) × (x)
the numerical coefficient of the first term is 1.
c) for given expression x + 3 + 7x,
the constant term = 3
d) for given expression x + 3 + 7x,
the like terms are x and 7x

Answer:
110 degrees
Step-by-step explanation:
Ok so no matter what the shape is, the exterior angles always have to add up to 360 degrees. Then, you can make the equation:
140 + 110 + x = 360
250 + x = 360
x = 110 degrees
Here's another way you can do it:
To do this, you can start by noticing that the top angle would be 40 degrees, because there's a straight line with 140 degrees and that angle, so you can do 180 - 140 = 40 degrees.
Then, the angle towards the bottom right would be 70 degrees using the same strategy:
180 - 110 = 70 degrees
The interior angles of a triangle always have to add up to 180 degrees, so you can do 180 - 40 - 70 = 70 to find the third interior angle of the triangle.
The last step is to do 180 - 70 = 110 to find the measure of the exterior angle at that point.
NOTE: Angles not necessarily drawn to scale.

3n+5-12n-8+6p
Answer
-9n-3+6p
Step-by-step explanation:
Answer:
-9n - 3 + 6p
Step-by-step explanation:
You have to remember that you can add or subtract only LIKE terms. In other words, you can't add 3n + 5, so separate them.
In this equation: 3n + 5 - 12n - 8 + 6p,
1. 3n - 12n
2. 5 - 8
3. 6p
= -9n - 3 + 6p
