Question

find the value of x so that - (3/4)^-9×(3/4)^-7=(3/4)^4x​

Answer 1

Step-by-step explanation:

(3/4)^9 ×(3/4)^-7 =(3/4)⁴x

TO FIND:

The value of x

Consider,

(3/4)^9 ×(3/4)^-7 =(3/4)⁴x

Using,

a^m ×a^n=am+n

(3/4)^9(-7) =(3/4)⁴x

(3/4)² = (3/4)⁴x

Equating powers on both sides , we get

4x=2

x=2/4

x=1/2
