Question

use square roots to answer each exercise (just type the final answer/number into the space) show work on paper!!!!!!!!!!!!!!!!!!!!!!!!! $3sqrt{16} - sqrt{36} = $ $ sqrt{400} + -5sqrt{196} = $ $ -3sqrt{49} \times -2sqrt{81} = $

Explanation:

Step1: Calculate square roots

$\sqrt{16}=4$, $\sqrt{36}=6$

Step2: Substitute and compute

$3\times4 - 6 = 12 - 6$

Step3: Calculate square roots

$\sqrt{400}=20$, $\sqrt{196}=14$

Step4: Substitute and compute

$20 + (-5)\times14 = 20 - 70$

Step5: Calculate square roots

$\sqrt{49}=7$, $\sqrt{81}=9$

Step6: Substitute and compute

$(-3)\times7 \times (-2)\times9 = (-21)\times(-18)$

Answer:

6
-50
