Question

find the value of x
​

Answer 1

Answer:

x= -2

Step-by-step explanation:

(2/7)⁻³ × (2/7)⁻¹¹ = (2/7)⁷ˣ

as bases are same and power are different so, lets add powers

(2/7)⁻³⁻¹¹ =(2/7)⁷ˣ

(2/7)⁻¹⁴ = (2/7)⁷ˣ

now as both sides bases are same hence powers should also be same,so

-14=7x (divide both side by 7)

-2=x
