To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

$\sqrt{200}=\sqrt{25*8} =\sqrt{25}*\sqrt{8}= 5*\sqrt{8} =5\sqrt{8}$

and

$4\sqrt{108}=4\sqrt{27*4} =4*\sqrt{27}*\sqrt{4}=4* \sqrt{9} *\sqrt{4}*\sqrt{3} =4*3*2*\sqrt{3}=24\sqrt{3}$

In triangle ABC, m?BAC = 50°. If m?ACB = 30°, then the triangle is triangle. If m?ABC = 40°, then the triangle is triangle. If t

kumpel [21]

use the pythagorean theorem: a^2 + b^2 = c^2

6^2 = 36

4^2 = 16

36-16 = 20.

the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
