Question

10^(-x+4) + 7 = 5 ?

Answer 1

is it 10 to the power of (-x+4) ?

Answer 2

@rox13kh yup

Answer 3

@mujjazi you have got it all wrong

Answer 4

you have
10^(-x+4) = -2

a^b is never negative if a>0
hence, for this one, no real values of x exits

Answer 5

exist*

Answer 6

@shubhamsrg So, it's not able to be worked out right?

Answer 7

well am sure you do not want to solve for the complex values of it ?
in layman language, yes, no real value of x exists which satisfies the given equation
