Answer:

6

Explanation:

We are given here a exponential equation and we need to find out the value of b in the equation. So the given equation is ,

⇒5⁶ × 5^b = 5¹²

⇒ 5^(6+b) = 5¹² [ using aⁿ × aⁿ' = a^(n + n') ]

On comparing the bases and powers we have ,

⇒ 6 + b = 12

⇒ b = 12 - 6

b = 6

Hence the value of b is 6 .
