Keep in mind the square root of x squared equals the absolute value of x.
So, solving this equation for x involves the following:
sqrt(x2)+4=4x
|x|+4=4x
Solving for |x| yields:
|x|=4x-4
Using x=4x-4:
-3x=-4, x=4/3.
Using x=-(4x-4):
x+4x=4
x=4/5
Checking both with the original equation shows that |4/3|+4=16/3=4*4/3, so x=4/3.
However, |4/5|+4=24/5, which does not equal 4*4/5, so x does not equal 4/5.
This means there is only one solution, x=4/3.

C equals the square root of 1000 or 31.622776601683793319988935444327...
'A' squared plus 'B' squared equals 'C' squared. If 'A' and 'B' are the legs of the right angle comprising the sides of the box, 30 inches squared (900) plus 30 inches squared (900) equals 1800. The square root of 1800 is 42.426408711929.
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
