Question

use square roots to answer each exercise (just type the final answer/number into the space) show your work!!!!!!!!!! \\(sqrt{81 + 19} - sqrt{100 - 75} =\\) \\(left( sqrt{49} - sqrt{169}
ight)^2 =\\) \\(7sqrt{36} + 5sqrt{144} =\\)

Explanation:

Step1: Calculate inside first square root

$\sqrt{81+19} = \sqrt{100} = 10$

Step2: Calculate inside second square root

$\sqrt{100-75} = \sqrt{25} = 5$

Step3: Subtract the two results

$10 - 5 = 5$

---

Step1: Compute each square root

$\sqrt{49}=7$, $\sqrt{169}=13$

Step2: Subtract inside parentheses

$7 - 13 = -6$

Step3: Square the result

$(-6)^2 = 36$

---

Step1: Compute each square root

$\sqrt{36}=6$, $\sqrt{144}=12$

Step2: Multiply by coefficients

$7\times6=42$, $5\times12=60$

Step3: Add the two products

$42 + 60 = 102$

Answer:

$5$
$36$
$102$
