Step-by-step explanation:    

Step 1: Add (-9)/8 to both sides.

(21/4) ^x + 9/8 = 2

(21/4) ^x + 9/8 + -9/8 = 2 + -9/8

(21/4) ^x = 7/8

Step 2: Solve Exponent.

(21/4) ^x = 7/8

x = log (7/8) by log (21/4)

x=−0.080527

Explanation in words:  

The first step is to Add (-9)/8 to both sides of the question. In the end, the answer will result as (21/4) ^x = 7/8.

The second step is to solve the equation by using log. Formula for log is log = x. For base. At the end we solve all the exponents and the answer will end up being x=−0.080527.
