Basic Math Examples

$1 = 3^{y}$

Step 1

Rewrite the equation as $3^{y} = 1$ .

$3^{y} = 1$

Step 2

Take the natural logarithm of both sides of the equation to remove the variable from the exponent.

$\ln (3^{y}) = \ln (1)$

Step 3

Expand $\ln (3^{y})$ by moving $y$ outside the logarithm.

$y \ln (3) = \ln (1)$

Step 4

Simplify the right side.
