Question

What is the value of the expression 2^2+8^2 divided by 2^2?

A. 8
B. 20
C. 17
D. 20

Answer 1

C. 17

Explanation:

To solve this, we first convert 8^2 to something to the power of 2. Since 8=2^3, then 8^2=2^6. So our expression looks like 2^2+2^6 now. Factoring out the 2^2, we get 2^2(1+2^4). Since our expression is divided by 2^2, we get (1+2^4) as our answer which can also be written as 17. So our answer is C.

Answer 2

`(2^2+8^2)/(2^2) =((2*2)+(8*8))/((2*2)) =(4+64)/(4) =(68)/(4)=17`

Your answer is C (if my starting equation was right)
