Exponential Equations

Front

What is an exponential equation?

Back

An equation in which a variable appears in the exponent, such as a^x = b.

Front

How do you solve the equation 8 = 2^(5x + 7)?

Back

Rewrite 8 as 2^3, then set the exponents equal: 3 = 5x + 7.

Front

What is the solution to the equation 8 = 2^(5x + 7)?

Back

x = -⅗.

Front

What is the base of the exponential equation 8 = 2^(5x + 7)?

Back

The base is 2.

Front

How do you solve (-3)^x = (-3)^13?

Back

Since the bases are the same, set the exponents equal: x = 13.
