Question

Jika 2logaritma3 = a dan 3logaritma5 = b,nyatakan dalam bentuk a dan b

a.2logaritma5=

b.30logaritma150=

c.100logaritma50=

Answer 1

A. 2log3 x 3log5 = ab
b. 3log150/3log30
= 3log50+3log3 / 3log3+3log10
= 3log5+3log10+1 / 1+3log2+3log5
=b+3log2+3log5+1 / 1+1/2log3+b 
= b+1/2log3+b+1 / 1+1/a +b
=b+1/a+b+1 / 1+1/a+b
