Use these logarithmic properties:
#color(blue)(log_e)x=color(blue)(ln)x#
#log^2x=(logx)^2#
#log(color(blue)x^color(red)a)=color(red)alogcolor(blue)x#
And these exponential properties:
#(x^color(red)m)^color(blue)n=x^(color(red)mcolor(blue)n)=(x^color(blue)n)^color(red)m#
#e^lncolor(blue)x=color(blue)x#
Here's the expression:
#color(white)=e^(log_e^2 9)#
#=e^(ln^2(9))#
#=e^(ln^2 9)#
#=e^((ln 9)^2)#
#=e^((ln (3^2))^2)#
#=e^((2ln3)^2)#
#=e^(2^2ln^2 3)#
#=e^(4ln^2 3)#
#=(e^(ln^2 3))^4#
#=(e^(ln3*ln3))^4#
#=((e^(ln 3))^ln3)^4#
#=((color(red)cancelcolor(black)e^(color(red)cancelcolor(black)cc(ln) 3))^ln3)^4#
#=(3^ln3)^4#
#=3^(4ln3)#
#=(3^4)^ln3#
#=81^ln3#
#~~124.93528000...#
Hope this helped!
