5 to the power of x subtract 5 to the power of negative x over 5 to the power of x plus 5 to the power of negative x all equals 8. Can anyone help me get started on this problem or help me work through it.

(5^x-5^-x)/( 5^x+5^-x)=8 (5^2x-1)/(5^2x+1)=8 Let 5^x = P P^2-1/P^2+1=8 8P^2+8=P^2-1 7P^2=-9 P^2=-9/7 P=+ or - 3i/sqrt7 we consider p=5^x hence 5^x=-3i/sqrt7 still if u need to calculate x value make an apply log on both sides.
