Exponential Equations Different Bases

To solve this exponential equation which cannot be changed into the same bases on both sides of the equal sign, you must _________________

• raise 2 to the power of x also.

• set x = 2

• divide by 3.

• take the logarithm of both sides.

• x = 2,40961

• x= 7,22882

• x= 2,40960

• x= 7,22881

Rewrite the exponential as a log.

2^3x+1 = 12

• ln(2)= 3x+1

• log₂(12)= 3x+1

• ln(6)=3x+1

• log₁₂(2)= 3x+1

• take the logarithm of both sides

• multiply both sides by 7

• divide both sides by 7

• add 1 to both sides
