Question

Rewrite each of the following as an exponential expression ( no fraction ):
1.) 1/4
2.) 2/x^3
3.) 1/(2x-3)^3
4.) 3x/(2x)^5

Answer 1

1.) 1/4 = 1/2² = 2^-2
2.) 2/x^3 = 2x^-3
3.) (2x - 3)^-3 ( if required to expand, do it and then change)
3 3
4.) 3x/(2x)^5 = 3x/32x^5 = ----- x ^(1-5) = ---- x^-4
