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.

$= 8^{15-8}$

$= 8^7$
