Answer:

The value of a is 10 and the value of b is 6

Explanation:

* Lets revise how to solve the problem

- Remember in the number with exponent

- a^n × a^m = a^(n + m)

- a^n ÷ a^m = a^(n - m)

Lets solve the problem


(7^(2).7x^(8))/(7x^(4))

- Lets use the rule above


7^(2).7^(8)=7^(2+8)=7^(10)


(7^(2).7^(8))/(x^(4))=(7^(10))/(7^(4))


(7^(10))/(7^(4))=(7^(a))/(7^(4))

∴ a = 10


(7^(10))/(7^(4))=7^(10-4)=7^(6)


7^(6)=7^(b)

∴ b = 6

* The value of a is 10 and the value of b is 6
