If 5^3b-1=5^b-3 what is the value of b? a. -2 b. -2 c. 1 d. 2

ANSWER



EXPLANATION

We want to find the value of b in the following exponential equation.



Since the base on both sides of the equation are the same.

We equate the exponents to get,



We group like terms to obtain,



This will simplify to,



We now divide both sides by 2 to obtain,

Hello : 
 5^(3b-1)=5^(b-3)
3b-1 = b -3
2b = -2
b = -1
