The value of n in n2 =121

Step-by-step explanation:

I'm assuming you mean n squared, so

Take the square root of both sides to cancel out the n squared.

n = ±11

It's plus or minus because -11 * -11 = 121, and 11 * 11 = 121.

11 or -11

Step-by-step explanation:

11*11 = 121

-11*-11 = 121

n can be 11 or -11
