Answer :
Answer: The square root of 121 is not 12. It is 11.
Step-by-step explanation:
Given [tex]\sqrt{121}[/tex], remember that:
[tex]\sqrt{x^2}=x[/tex]
[tex]\sqrt[n]{x}=x^{\frac{1}{n}}[/tex]
As we know, the number 121 can be rewritten in the following form:
[tex]121=11*11=11^2[/tex]
Therefore, you need to rewrite this and then simplify. Then, you get:
[tex]\sqrt{121}=\sqrt{11^2}=11^{\frac{2}{2}}=11^1=11[/tex]
Then, the square root of 121 is not 12. It is 11.
