Question

Solve the exponential equation. 4x = 0.5 -2 -1 -1/2

Answer 1

Answer:

$x=-1/2$

Step-by-step explanation:

$4^x=1/2$

Make the bases 2 on both sides of the equation.

$2^{2^x}=2^{-1}$

Multiply the exponents.

$2^{2x}=2^{-1}$

Cancel the bases.

$2x=-1$

Divide 2 into both sides of the equation.

$x=-1/2$
