**Damon**, Friday, April 27, 2012 at 11:02pm1.)Prove that log15=log5+log3

hey 15 = 3 * 5

log a b = log a + log b

2.)Show that log10800=4log2+3log3+2log5

log (2^4*3^3*5^2)

log (16*27*25)

log (10800)

3.)show that log108/605=2log2+3log3-log5-2log11.

log [ 2^2*3^3 /(5*11^2) ]

log [ 4*27/(5*121) ]

log [ 108 / 605 ]

all of this is just

log a*b = log a + log b

and

log a^n = n log a
