Solve for x 3^x=7

Problem

3=7

Solution

1. Apply the logarithm to both sides of the equation to isolate the variable x You can use the natural logarithm ln()

ln(3)=ln(7)

2. Use the power rule of logarithms, which states that ln(ab)=b*ln(a) to move the exponent x in front of the logarithm.

x*ln(3)=ln(7)

3. Isolate x by dividing both sides of the equation by ln(3)

x=ln(7)/ln(3)

Final Answer

x=ln(7)/ln(3)
