Question

Which of the expressions have a value of 2?
​

Answer 1

E. √4

B. ³√8

Explanation:

You can find this simply by putting it into a calculator if you have access to one. Just type √ and 4. If you don't have a calculator, you can just use the knowledge that 2 × 2 = 4, hence why it's the square root of 4 :)

You can also determine that B is correct by doing 2 to the power of 3.

2³ = 8, so you know that B is correct too.

Answer 2

The answers are B and E

Explanation:

The square root of 4 is 2.

The cube root of 8 is 2.

A is wrong because its value is 4.

C is wrong because its value is 4.

D is wrong because the square root of 8 isn't whole.
