1.)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
