Simplify<br><br> sqrt(3 + 2 sqrt 2) ...?

trasher [3.6K]

The answer is 1 + √2

sqrt(2) is $\sqrt{2}$
sqrt(3 + 2 sqrt 2) is $\sqrt{3 +2 \sqrt{2} }$
Now, let's simplify $\sqrt{3 +2 \sqrt{2} }$ .
We will use square of sum: (a + b)² = a² + 2ab + b²

$\sqrt{3 +2 \sqrt{2} } = \sqrt{1+2+2 \sqrt{2} }= \sqrt{1+2 \sqrt{2}+2 }= \\ 
= \sqrt{1^{2} +2*1* \sqrt{2} + (\sqrt{2} ) ^{2} } = \sqrt{(1+ \sqrt{2}) ^{2}} =1+ \sqrt{2}$

a giant pizza box in the shape of a rectangular prism measures 38m times 38m times 0.25m. what is the surface area of the box

Helga [31]

So the surface area of a box has this equation: A = 2 (wl + hl + hw)

w = width = 38
l = length = 38
h = height = 0.25

Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
= 2926 square meters
