Question

find square root of √5-2​

Answer 1

Answer:

First, you want to figure out what the number is we are taking the square root of. In this case, it is this (-5)^2. So, we square -5 and get 25.

Secondly, recognize that you can have zero roots, one root, or (most commonly) two roots. Since we are working with a non-zero, non-negative number, we have two roots. Zero is the only number with one root (zero), and negative numbers have no real roots.

Answer 2

Step-by-step explanation:

√5-2 = √5-2

= (√3)^2

= 3
