ln(8x) = n
8x = eⁿ
x = eⁿ/8
a.) ln(8x) = 1
raise both sides of the equation by e and you'll get
8x = e ; therefore x = e/8
b.) ln(8x) = 2
raise both sides of the equation by e and you'll get
8x = e^2 ; therefore x= (e^2)/8
c.) ln(8x) = -1
raise both sides of the equation by e and you'll get
8x = e^-1 ; therefore x = 1/8(e) with e in the denominator.
d.) ln(8x) = 0
raise both sides of the equation by e and you'll get
8x = 1 ; therefore x = 1/8
