Jika log a- log b= 15 maka nilai dari log²a- log²b/ log a²✓b - log b²✓a

log a - log b = 15
log²a- log²b/ log a²✓b - log b²✓a

__log²a-log²b___ =
log a²✓b - log b²✓a

__2(log a - log b)___=
log(a²:b²)+log(√b:√a)

________30_________
2(log a - log b)+log√b-log√a

_________30_________
30+(log a - 15)/2 - (log a)/2

_30_ = _30_ =
30-7,5 22,5
_4_= 1,332
3

log a = 15 + log b
log b = log a - 15
