Question

if 5 power x +1 +5 power x-1 ​

Answer 1

Answer:

i think x = 3

Step-by-step explanation:

5^x+1 + 5^x-1 = 650

we can write it as,

5^x+1 + 5^x-1 = 625 + 25 = 5^4 + 5^2

now compairing lhs and rhs we get ,

5^x+1 = 5^4 and 5^x-1 =5^2

as bases are same we can write it as;

x+1=4 and x-1=2

adding both we get 2x = 6

x=6/2 = 3
