The question is asking which of the answer choices is NOT equivalent to
  2^-3 = 1/(2^3) = 1/8

You can determine this by expressing each of the answer choices in a manner that lets you compare them to 2^-3 or to 1/8.

A. -2^3 = -8 . . . . . this is not equivalent to 2^-3 or 1/8. This is the appropriate selection.

_____
Let's check the others, just to be sure.
B. 2(1/4)^2 = 2(1/16) = 2/16 = 1/8 . . . . is equivalent to 1/8

C. 2^2 × 2^-5 = 2^(2-5) = 2^-3 . . . . is equivalent to 2^-3

D. (1/2)^3 = 1/2^3 = 1/8 . . . . is equivalent to 1/8

Our choice of A is correct, as all these other choices are equivalent to the given expression.

Pls help me divide this radical and pls show work
Alenkinab [10]
Let's start by rationalizing the radical:

4√6/√50 * √50/√50

This gets rid of the radical in the denominator, giving us:

4√300/50

√300 can be simplified to √3 * √100 or 10√3. Now we can insert this back into the numerator:

4 * 10√3/50

This is equivalent to:

40√3/50

40/50 can be simplified to 4/5.

Therefore, the answer is 4√3/5.

Maurice's new CD has 12 songs. Each song lasts between 3 and 4 minutes. He estimates that the whole CD is about 30 minutes long.
nlexa [21]

Answer:

The estimate is less than the actual length of the CD.

Step-by-step explanation:

Consider the provided information.

Maurice's new CD has 12 songs. Each song lasts between 3 and 4 minutes.

That means the minimum length of the CD should be: 12×3=36 minutes.

The maximum length of the CD should be: 12×4=48 minutes

He estimates that the whole CD is about 30 minutes long.

30 minutes is less than 36 minutes.

That means, the estimate is less than the actual length of the CD.

Hence, the correct statement is: The estimate is less than the actual length of the CD.
