Answer:
6 OR 3. Read explanation
Step-by-step explanation:
12-(3*2)=12-6=6
But I am guessing there may be a formatting error and you are trying to find y^2, so here goes.
12-(3^2)=12-9=3

The question says “write with prime number base” and the question is 8 square root 32 (7,d)
Answer:
[tex]2^{\frac{11}{2}}[/tex].
Step-by-step explanation:
We need to write the given expression with prime number base.
In question 7, part d.
The given expression is
[tex]8\sqrt{32}[/tex]
It can be rewritten as
[tex]2^3\sqrt{2^5}[/tex]
Using properties of exponents , we get
[tex]2^3(2^5)^{\frac{1}{2}}[/tex]
[tex]2^3(2^{\frac{5}{2}})[/tex] [tex][\because \sqrt[n]{x}=x^{\frac{1]{n}}][/tex]
[tex]2^{3+\frac{5}{2}}[/tex] [tex][\because (a^m)^n=a^{mn}][/tex]
[tex]2^{\frac{6+5}{2}}[/tex] [tex][\because a^ma^n=a^{m+n}][/tex]
[tex]2^{\frac{11}{2}}[/tex]
Here, base is 2 and it is prime number.
Therefore, the required expression is [tex]2^{\frac{11}{2}}[/tex].
do the ratios 1/3 and 2/9 form a proportion

What is the completely factored form of 3x^5-7x^4+6x^2-14x?
Answer:
x(x - 7)(x^3 + 2)
Step-by-step explanation:
Note that x is a common factor here:
3x^5-7x^4+6x^2-14x = x(3x^4 - 7x^3 + 6x - 14), or:
x(3x^4 - 7x^3 + 6x - 14) Note that 6x - 14 can be rewritten as 2[x - 7]
and that 3x^4 - 7x^3 can be rewritten as x^3[x - 7]
Therefore, x(3x^4 - 7x^3 + 6x - 14 becomes:
x(x - 7)(x^3 + 2)

Answer:
TFtgsbhjz whatt
Step-by-step explanation:
The correct symbol for the unit conversion is given by 2000 lb = 1 T
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the symbol be represented as A
Now , the weight of the object is given by
Let the first weight be p = 2000 lb
Let the second weight be q = 1 Ton
And , from the unit conversion
2000 lb = 1 Ton
So , the value of q = p
Hence , the symbol is equal to and 2000 lb = 1 Ton
