Question 171549: 6^x=15

You can put this solution on YOUR website! 6^x = 15
The exponential expression (that is 6^x) is already isolated on the left side of the equation. It is called an exponential expression because the exponent is a variable and not a number.
We take the natural log of both sides of the equation.
ln means NATURAL LOG for short.
ln(6^x) = ln(15)
Bring down the exponent on the left side.
x(ln6) = ln(15)
Divide both sides by the coefficient of x or ln6.
x = ln15/ln6
x is approximately 1.5114
