Solve for x 8^(3x)=360
Problem
Solution
Apply the logarithm to both sides of the equation to isolate the exponent. We will use the natural logarithm (
ln() .
Use the power rule of logarithms, which states that
ln(ab)=b*ln(a) to move the exponent in front of the logarithm.
Isolate the variable
x by dividing both sides of the equation by3*ln(8)
Simplify the expression using the property
3*ln(8)=ln(8) Since8=512 the denominator can be written asln(512)
Calculate the numerical value using a calculator for an approximate decimal answer.
