Question

find the value of x.

Answer 1

heya mate hope it helps u

Answer 2

Heya

(-7/8)^2+x = (-7/8)^3 [(-7/8)^2/3 ÷ (-7/8)^-1/3]

=> (-7/8)^2+x = (-7/8)^3 [(-7/8)^2+1/3]

=> (-7/8)^2+x = (-7/8)^3 [(-7/8)^3/3]

=> (-7/8)^2+x = (-7/8)^3 × (-7/8)

=> (-7/8)^2+x = (-7/8)^3+1

=> (-7/8)^2+x = (-7/8)^4

Since bases are same.

=> 2 + x = 4

=> x = 4 - 2

=> x = 2
