Answer 2

Step-by-step explanation:

(81) ÷ (9) = 9^2x

(9)² ÷ (9)¹ = (9)^2x

• WKT, Using the law of exponents:-[a^m÷a^n=a^m-n]

(9)^2 -1 = (9)^2x

(9)¹ = (9)^2x

• Now evaluate power:-

1 = 2x (transposing '2x' to the RHS)

1 -2x = 0

-2x = -1 (transposing '1' to the LHS)

x = -1/-2 (transposing '-2' to the LHS)

• Here's ur answer:- x = 1/2
