The expression (2^6x)^3x can be written as 2^f(x), where f(x) is a function of x. Determine f(x).

Question

I have no idea how to do this as the only way I thought of was f(x) = 6x^3x but since there's a bracket, the 3x can't work out. How do I solve this?

Answer 1

f(x)=18x²

Remember: (a^m)ⁿ = a^mn
