Question

if you are writing equivalent expression for 2^3 · 2^4, how many times would you write 2 as a factor?

Answer 1

7 times

Explanation:

In order to find the answer to this question you have to remember that when dealing with exponents you need to multiply the number to itself as many times as the exponent. In this case we have 2^3 we then need to multiply two by itself three times because three is it's exponent.

`2^3 *2^4`

`2^3=2*2*2`

`2^4=2*2*2*2`

`2*2*2*2*2*2*2=`

`3+4=7`

`=7`

Hope this helps.
