ln(1/25) = ln(5^-2) = -2 ln(5)
e^(3ln2) = e^(ln8) = 8
given that ln2=0.7 and ln5=1.6, find:
1) ln(1/25)
2) e^3ln2 - ln5

steve can you help me out with a question
im confused on how you got 8 for the second problem. may you please explain?
3ln2 = ln 2^3 = ln8
by definition,
e^lnx = x
ln(e^x) = x
ln and e^ are inverse functions

e^lnx = x
