Answer:

\sqrt{10+4\sqrt{6 } = 4.44948

or = \sqrt{6}  + 2

<em>step by step...solving </em>

<em>10 + 4</em>\sqrt{6}<em />

<em>add/subtract </em>\sqrt{6}<em>² = 6</em>

<em>=10 + 4</em>\sqrt{6}<em> + </em>\sqrt{6}<em>² - 6</em>

<em>Refine</em>

<em>= </em>\sqrt{6}<em> ² + 4</em>\sqrt{6}<em> + 4</em>

<em>rewrite </em><em>↑</em><em> as </em>\sqrt{6}<em>² + 2</em>\sqrt{6}<em> * 2 + 2²</em>

<em>apply Perfect Square Formula (a + b)² = a² + 2ab +²</em>

<em>a = </em>\sqrt{6}<em>, b=2</em>

<em>= (</em>\sqrt{6}<em> + 2)²</em>

<em>= </em>\sqrt \sqrt({6}+ 2)<em>2square    </em>

<em>(the 2 square would not fit like i wanted it to)</em>

<em>apply radical rule </em>\sqrt[n]{a^{n} } = a<em>, assuming a ≥ 0</em>

<em>= </em>\sqrt{6} + 2<em />

posting others as picture (have an account with Symbolab to help me as well.  Just taking too long to type in the step by step if you need it.  all pictures have the decimal result.

If Sam buys 200 stickers at $10 and sells them for $.25 each how much is he making?
Alex17521 [72]
First you will need to multiple 200 by .25 to see how much money Sam will make.
200 x .25 = $50 
now you need to subtract that price by 10 because he spent $10 to get the stickers.
50 - 10 = $40
Sam is making $40 off the stickers.
let me know if you have any other questions
