How do you solve #2sqrt(4x)=20#?

Answer 1

Savannah Anderson

#color(blue)(x=25#

#2sqrt(4x)=20# Squaring both sides

#2^2(sqrt(4x))^2=20^2#

#4 * 4x=400#

#16x=400#

#x=400/16#

#color(blue)(x=25#

To solve the equation 2√(4x) = 20, you can follow these steps:

Divide both sides of the equation by 2 to isolate the square root term: √(4x) = 10.
Square both sides of the equation to eliminate the square root: 4x = 100.
Divide both sides of the equation by 4 to solve for x: x = 25.

Therefore, the solution to the equation 2√(4x) = 20 is x = 25.
