Question

Which of the following expressions are equivalent? Justify your reasoning.
a. 4 square root of x^3
b. 1/x^-1
c. ^10 square root x^5*x^4*x^2
d. x^1/3*x^1/3*x^1/3

Answer 1

I found two that are equivalent.
Note: that 1/x^-1 is the same as 1x^1 or just plain x
Now you find the other one that simplifies to x.

Answer 2

Hint: when multiplying expressions like x^n add the exponents
