Answer: The square root of 121 is not 12. It is 11.

Explanation:

Given
√(121) , remember that:

√(x^2)=x

$\sqrt[n]{x}=x^{(1)/(n)}$

As we know, the number 121 can be rewritten in the following form:

121=11*11=11^2

Therefore, you need to rewrite this and then simplify. Then, you get:

$√(121)=√(11^2)=11^{(2)/(2)}=11^1=11$

Then, the square root of 121 is not 12. It is 11.
