**Reiny**, Thursday, March 14, 2013 at 8:22amI will do the second one

324 = 4(81)

= 2^2 x 3^4

log324 = log(2^2 x 3^4)

= log 2^2 + log 3^4

= 2log2 + 4log3

= 2(.3010) + 4(.4771)

= .6020 + 1.9084

= 2.5104

log(450) = log(10x45)

= log(10x9x5)

= log10 + log 3^2 + log5 ---> need log5

other combinations:

450 = 5^2 x 9x2 = 5^2 x 3^2 x 2 --- still need log 5
