Answer
$a^6\times a^2=a^{8}$
Work Step by Step
$a^6\times a^?=a^{8}$
To multiply powers with the same base, we add the exponents. This means that the sum of $6$ and the second exponent must be equal to $8$. This is only true if the second exponent is $2$ because $6+2=8$
This gives us the equation $a^6\times a^2=a^{8}$
