Question

Can someone help with this please

Answer 1

Answer:

Step-by-step 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

Answer:

$3^2$

Step-by-step explanation:

$\frac{3^8*\:3^4}{3^2*\:3^8}$

Apply Exponent rule: $a^b\cdot \:a^c=a^{b+c}$

$\frac{3^{12}}{3^8* \:3^2}$

$\frac{3^{12}}{3^{10}}$

Apply exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$3^{12-10}=3^2$
