How do you express 8^k x 3^3k, as a power of 6?

Because 8^k and 3^3k do not share the same integer they must be changed to share the integer make them both either X^k or X^3k And because 8 = 2^3, 8^k becomes 2^3k x 3^3k Now because they have the same integer they can be multiplied and = 6^3k – a power of 6
