Question

can you please solve this problem

Answer 1

the given can be rewritten as [ 5^(2x)]/25=[5^(2x)]/5-100
let 5^(2x) = t
t/5-t/25=100
4t=2500
t=5^4
x=2

Answer 2

= 100 = 5^(2x-1) - 25^(x-1)

= 125 - 25 = 5^(2x-1) - 25^(x-1)

= 5^3 - 5^2 = 5^(2x-1) - 25^(x-1)

Gets substitute,

= 5^3 = 5^(2x-1)

= 3+1 = 2x

= 4/2=2=x.
U may do it by both.

Hope it's helpful to u.
