Question

Rewrite the radical expression as an exponential expression, and then simplify.

Answer 1

The third answer option is correct.  sqrt(x) = x^(1/2).  So sqrt(121) = 121^(1/2).

Answer 2

Exponential expression and simplify value for the given radical expression is $\sqrt{121}= (121)^{\frac{1}{2} } = 11$

What is exponent?

" Exponent is defined as the given number is multiplied given number of times , the power on the number represents the number of times."

According to the question,

Given radical expression,

$\sqrt{121}$

Represent it in exponent expression we get,

$(121)^{\frac{1}{2} }$

Simplify  value of the exponential expression ,

$(121)^{\frac{1}{2} } = ((11)^{2})^{\frac{1}{2} }$

          $= 11$

Hence, exponential expression and simplify value for the given radical expression is $\sqrt{121}= (121)^{\frac{1}{2} } = 11$
