\left(4x\right)^{2}=\left(3\sqrt{x}\right)^{2}
Square both sides of the equation.
4^{2}x^{2}=\left(3\sqrt{x}\right)^{2}
Expand \left(4x\right)^{2}.
16x^{2}=\left(3\sqrt{x}\right)^{2}
Calculate 4 to the power of 2 and get 16.
16x^{2}=3^{2}\left(\sqrt{x}\right)^{2}
Expand \left(3\sqrt{x}\right)^{2}.
16x^{2}=9\left(\sqrt{x}\right)^{2}
Calculate 3 to the power of 2 and get 9.
16x^{2}=9x
Calculate \sqrt{x} to the power of 2 and get x.
16x^{2}-9x=0
Subtract 9x from both sides.
x\left(16x-9\right)=0
Factor out x.
x=0 x=\frac{9}{16}
To find equation solutions, solve x=0 and 16x-9=0.
4\times 0=3\sqrt{0}
Substitute 0 for x in the equation 4x=3\sqrt{x}.
0=0
Simplify. The value x=0 satisfies the equation.
4\times \frac{9}{16}=3\sqrt{\frac{9}{16}}
Substitute \frac{9}{16} for x in the equation 4x=3\sqrt{x}.
