Question

find the value of x , if 2 ^7x-5 =( 32)x-7​

Answer 1

Answer:

the value of x is -15

Step-by-step explanation:

32 can be written as 2⁵. so on the Right hand side of the equation write 32^(x-7) as 2^(5*(x-7))

2^(7x-5) = 2^(5x-35)

Bases are equal. So powers can be equated.

this implies

7x-5=5x-35

2x=-30

x=-15
