Work Step by Step

Exponents signify repeated multiplication. An exponent signifies how many times a number is multiplied by itself. In this expression, $8\times8\times (x-1)\times (x-1)\times (x-1)$, $8$ is multiplied by itself twice, and $x-1$ is multiplied by itself $3$ times. In exponential form, we rewrite this using $8^2(x-1)^3$.
