Question

if (5/4) power -5 ×(5/4) power -10 = (5/4) power 3x, then find the value of x​

Answer 1

Answer:

5

Step-by-step explanation:

(5/4)^(-5) * (5/4)^(-10) = (5/4)^3x

since the base is same

therefore,

(-5) + (-10) = 3x when the base is same then in multiplication, powers are added.

=> 15=3x

=> x= 5
