8=1+sqrt(r/4)

Solution

8 = 1 + \frac{r}{4}

Solution

r = 196

Solution steps

8 = 1 + \frac{r}{4}

Switch sides

1 + \frac{r}{4} = 8

Move

1

to the right side

\frac{r}{4} = 7

Square both sides:

\frac{r}{4} = 49

\frac{r}{4} = 49

Solve

\frac{r}{4} = 49 : r = 196

r = 196

Verify Solutions:

r = 196

True

The solution is

r = 196

(x^2+7)^{1/2}=4

(x^{2} + 7)^{\frac{1}{2}} = 4

3/(sqrt(x+1))-1=2

\frac{3}{x + 1} - 1 = 2

x^2-6x+9=sqrt(3-x)

x^{2} - 6 x + 9 = 3 - x

sqrt(x-2)+sqrt(2x+3)=4

x - 2 + 2 x + 3 = 4
