Question

Expressions equivelant to 64^x

Answer 1

$64^{\text{x}} = (8^2)^{\text{x}} = 8^{2\text{x}}$

The rule used is that $(a^b)^c = a^{bc}$ we multiply the exponents b and c.

Or we could say this

$64^{\text{x}} = (4^3)^{\text{x}} = 4^{3\text{x}}$

Or,

$64^{\text{x}} = (2^6)^{\text{x}} = 2^{6\text{x}}$

Therefore, we have multiple possible answers.
