Question

Prove that x = 2:
3^(x/2) + 1 = 2^x

Answer 1

3^ (2/2) + 1 = 2^2 this should work think you can try to solve from here?

Answer 2

Sorry, i should have expressed myself better, i need an expression for the value of x, i mean, isolate x in this expression

Answer 3

i see, so grouping it should work like 1 =3^(2/2) - 2^2 ( i would still fill in x for 2 because it is already given

so what is 3 ^1?

Answer 4

ok i have this backwards

Answer 5

Don't worry, i know how to plug in the value. I was just wondering if there is any way to isolate x, but apparently it's not possible. But thanks man!

Answer 6

I the expression was more complex, maybe the only solution would be a numerical method, such as Newton's method

Answer 7

i would think that 3 -2 before the exponents would work
