Can someone simplify the following expression.

Step-by-step explanation:

9^(1/2) =3

this expression is :  3(r^(5/2) ×r^(-1) )(t×t^(1/2))

3r^(5/2 - 1)×t^(1+1/2)

3^(1/2)×t^(3/2) answer : 2

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60
