First you want to subtract 36
so it looks like this
Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)
which is equal to
Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]
Then you end up with the equation 4x+164=256
Then subtract 164 to both sides
4x=92
then divide 92 by 4
Then you get x=23
