#color(blue)(x=e^((ln(0.422))/0.6223)~~0.2499763052)#

#3x^(0.6223)=1.266#

Divide by 3:

#x^(0.6223)=0.422#

Taking natural logarithms of both sides:

#0.6223ln(x)=ln(0.422)#

Divide by #0.6223#:

#ln(x)=(ln(0.422))/0.6223#

Raising #bbe# to the power of each side:

#e^(ln(x))=e^((ln(0.422))/0.6223)#

#x=e^((ln(0.422))/0.6223)~~0.2499763052#
