Question

Can someone help with this please

Answer 1

Explanation:

3^8 * 3^4

ـــــــــــــــــــــ

3^2 * 3^8 =

3^(8+4)

ـــــــــــــــــــــ

3^(2+8) =

3^12

ـــــــــــــــــــــ

3^10 =

3^2

Answer 2

`3^2`

Explanation:

`(3^8*\:3^4)/(3^2*\:3^8)`

Apply Exponent rule:
`a^b\cdot \:a^c=a^(b+c)`

`(3^(12))/(3^8* \:3^2)`

`(3^(12))/(3^(10))`

Apply exponent rule:
`(x^a)/(x^b)=x^(a-b)`

`3^(12-10)=3^2`
