Question

2 square root of x-4 +16= 32

Answer 1

can u put parenthesis around what's under the square root symbol?

Answer 2

I'm guessing you meant 2 sqr root(x-4)+16=32

first divide each side by 2 yielding:
sqr root(x-4) +8=16

subtract 8 from each side:
sqr root(x-4)=8

Square both sides:
x-4=64

add 4 to each side
x=68
