Question

Which of the following is equivalent to √8?
A.2
B.√2
C.2 √2
D.2 + √2

Answer 1

`C.2√(2)`

Explanation:

Step 1: Know you can split 8 into factors of 4 and 2

`√((4)(2))`

Step 2: Recognize 4 is a square number

`\sqrt{(2^(2))(2) }`

Step 3: Because
`2^(2)` is squared you can move it out

`2√(2)`

Therefore the answer is C
