Question

Which of the following expressions are equivalent? Justify your reasoning.

A. 4√x3

B. 1/(x^-1)


C. 10√x5•x4•x2

D. x^1/3* x^1/3* x^1/3

Answer 1

for D, when you multiply powers of the same bases together, add the powers together

x^a * x^b * x ^c = x^(a + b + c)

Answer 2

For B)
When you move a base to a power to the other side of the fraction, change the sign on the power

Answer 3

so x^3/3 ?

Answer 4

1 / x^(-a) = x^(+a)

Answer 5

yes, what is 3/3

Answer 6

B and D are both X, correct?

Answer 7

yep

Answer 8

so thats the answer? just B and D?

Answer 9

Answer 11

A is X^(3/4)

and

C has a 10 coefficient, so those are not the same

Answer 12

as any other
