Question

Aku mau minta cara no 14-16 please

Answer 1

14)
log 2= p
log 3= q

³log 12=...?
= log 12/log 3
= log (4×3)/log 3
= log 2²+log 3/log 3
= 2.log 2+log 3/log 3
= 2p+q / q (A)

15) ³log 1/27=...?
= ³log 27⁻¹
= ³log (3³)⁻¹
= ³log 3⁻³
= -3.³ log 3
= -3.1= -3 atau 1/3

16) 4⁻²= 1/16
bᵃ= c
ᵇlog c= a

= ⁴log 1/16= -2 (A)
