Peter and James are 14 years apart, so that means when James is 14, Peter will be twice his age. 14 - 6 = 8. Peter will be twice James' age in 8 years.

Please help with the following problem asap!!

Answer:

$8^7$

Step-by-step explanation:

$\dfrac{8^{15}}{8^7 \cdot 8} =$

Remember that $8 = 8^1$ .

$= \dfrac{8^{15}}{8^7 \cdot 8^1}$

When you multiply powers with the same base, add the exponents. Do this in the denominator.

$= \dfrac{8^{15}}{8^{7+1}}$

$= \dfrac{8^{15}}{8^{8}}$

When you divide powers with the same base, subtract the exponents.

$= 8^{15-8}$

$= 8^7$
