Question

If 5^3b-1 equals 5^B -3 what is the value of B?

• -2
• -1
• 1
• 2 

Answer 1

b=-1

Explanation:

set 3b-1 and b-3 equal to each other because they have the same base which is 5.

3b-1=b-3

2b=-2

b=-1

Answer 2

The value of B is -1.

Here's how to solve it:

5^(3b-1) = 5^(B-3)

Since the bases are equal, we can set the exponents equal to each other:

3b-1 = B-3

Adding 3 to both sides, we get:

3b+2 = B

Therefore, the value of B is -1.
