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

Working over the real numbers, expressions B and D are (almost) equivalent.

They're not quite equivalent when x=0 as the first is undefined, but we'll let that go because we can't argue with the online system.

B and D

B )

x / x^-1 = x^1 = x

D)

x^1/3 * x^1/3 * x^1/3

= x^(1/3 + 1/3+ 1/3)

= x^3/3

= x^1

=x

Answer is B and D are equivalent

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

the answer is 3/2 and for decimal: 1.5
