Question

Jika ^2 log 3 = a dan ^2 log 5 = b, nyatakan bentuk berikut dalam a dan b

A. ^2log 15
B. ^4log 75
C. ^25log 36
D. ^2log 5

Answer 1

A. 2log15=2log3+2log5=a+b
b. 4log75=4log3+2*4log5=a/2+b
c. 25log36=25log4+25log9=(1/b)+(a/b)=(a+1)/b
d. 2log5=b

Answer 2

A. 2log15 = 2log3x5 = 2log3 x 2log5 = a x b
B. 4log75 = 2^2log5^2.3 = 2 x 2 x 2log5 x 2log3 = 4 x b x a
C. 25log36 = 5^2log9x4 = 2 x 5log9 x 5log4 = 2 x 5log3^2 x 5log2^2 = 2 x 2 x 2 x 5log3 x 5log2.................... gatauuu
D. 2log5 = b
