18. What is the simplified form of the following expression? (1 point) (5/4)^3

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
