Answer 2

Answer:

x= -5

Step-by-step explanation:

(7^2x÷7⁷)/7^4x =7³

7^2x÷7⁷=7³×7^4x

L.H.S.[ In case of divide if base (7) is same then power is substrates]

7^2x-7=7³×7^4x

R.H.S.[ In case of multiply if base(7) is same then power is added]

7^2x-7=7^3+4x

Now both side base is same so power can be taken equally...

2x-7=3+4x

-7-3=4x-2x

-10=2x

x= -10/2

x = -5
