Question

if 25n minus 1 + 100 is equal to 52n-1 find n ans n=2

Answer 1

25n-1+100=52n-1
25n+99=52n-1
25n-52n=-99-1
-27n=-100
n=100/27
n=3.70

Answer 2

Hey there,

Your answer.

-》25n-1+100 = 52n-1

-》25n-52n = -1+1-100

-》-27n = -1+(-99)

And we know that (+,-) is always be (-)

-》Then,-27n = -1-99

-》Then, -27n = -100

-》-27n = -100

( -,- ) Will get cut .

-》n = 100/27

:-) Hope it helps !
