Exercises Numbers, fractions and percents

Example 5.69 from Prealgebra, 5.7 Simplify and Use Square Roots

Simplify and Use Square Roots: example 5.69

Simplify: ⓐ $\sqrt{25}$ ⓑ $\sqrt{121} .$

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution

ⓐ

$\sqrt{25}$

Since $5^{2} = 25$ $5$

ⓑ

$\sqrt{121}$

Since $11^{2} = 121$ $11$

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Simplify: ⓐ $\sqrt{36}$ ⓑ $\sqrt{169} .$

How did it go?
