inverse of y=4^x

Solution

inverse

y = 4^{x}

Solution

\frac{ln ( x )}{2 ln ( 2 )}

Solution steps

y = 4^{x}

Replace

x

with

y

x = 4^{y}

Solve for

y, x = 4^{y}

\frac{ln ( x )}{2 ln ( 2 )}

Popular Examples

critical f(x)=x^3-x critical points

f (x) = x^{3} - x

range of 1/(4-x^2)range

\frac{1}{4 - x ^{2}}

domain of y=x^3-4x domain

y = x^{3} - 4 x

inverse of f(x)=3(x+8)^7 inverse

f (x) = 3 (x + 8)^{7}

asymptotes of f(x)=(x+2)/(x^2+2x-8)asymptotes

f (x) = \frac{x + 2}{x ^{2} + 2 x - 8}
