What is the square root of 141?

Answers

The square root of 141 = $√(141)$

This is because the two factors are 3 and 47, which both aren't perfect squares. You cannot take anything out.

If you want it simplified (like with a calculator) it would be:
$√(141) =11.87$

The square root of 141
√141=11.87434208703792
