Exponential Equations Change of Base

To solve 8 = 2^5x+7, you would need to re-write 8 as what base?

• 8

• 4

• 2

• Cannot be determined

Solve:

16^x-3 = 8^x-3

• 9

• -3

• 3

• 0

Solve: 9^8-x = 27^x-3

• x = - 5

• x = 5

• x = 1/5

• x = - 1/5

Solve for a:
5^{a + 2} = 1/125

• -1

• -6/7

• -5

• 4

• 4/3

• -4/3
