Answer: 1 Mark

Here we know that for any non zero number if the base is same and the number is multiplied, then the exponents are added.
$\left(8\right)\times \left(8\right)\times \left(8\right)\times \left(8\right)\times \left(8\right)$

$=2^3\times 2^3\times 2^3\times 2^3\times 2^3$

$=2^{3+3+3+3+3}$

$\because a^b\times a^c=a^{b+c}$

$=2^{15}$
