The square root of a number X, is the number Y that, when multiplied by itself, gives the number X.

For example, 10 * 10 = 100, so 10 is a square root of 100
Notice that 11 * 11 = 121, so the square root of 120 is close to 11.

Your calculator might have a square root button.

√120=√10.10.4.5
=√2.2.2.2.5.5.5
=2.2.5√5
=4.5√5
=20√5 Ans

√120 = √(4 x 30) = 2√30 is EXACT answer.

If taken further, will obtain an APPROXIMATE answer.

2 * sqrt(30)

√120
= √(2^2 x 2 x 3 x 5)
= 2√(2 x 3 x 5)
= 2√30

Krish has completely balls up his surd answer!!

rt 120 = rt (30 x 4) = 2 rt 30 which is simplest surd form

(btw 20 rt 5 = rt 2000)!!!


edit: krish's answer has disappeared

use a calculator press the square root button and type 120, if it comes out as a Surd or fraction-press S>D and the answer is: 10.95445115

10.95445115 = 10.95 (2 decimal place)

√120 = 2√30 = 10.95445115 per my calculator
