Solve for x: 3 3 x + 1 = 81
Solve for x:
3 3 x + 1 = 81
Step 1: Represent 81 exponentially with a base of 3 3⋅3⋅3⋅3 = 81 , therefore 34 = 81 Step 2: Set the exponents equal to each other and solve for x 3 3 x + 1 = 3 4 3x + 1 = 4 3x = 3 x = 1
Step 1: Represent 81 exponentially with a base of 3
3⋅3⋅3⋅3 = 81 , therefore 34 = 81
Step 2: Set the exponents equal to each other and solve for x
3 3 x + 1 = 3 4
3x + 1 = 4
3x = 3
x = 1
