HELP ME Tolong pakai cara

AB^-1 = 1
A = 1 . B
(log b .... 2) = 1 . (xloga .......... log(2a - 2)^2)
(-loga .... 1) ........ (log1/(b - 4) ....................... 1)

2 = log(2a - 2)^2
log 10^2 = log (2a - 2)^2
10^2 = (2a - 2)^2
10 = 2a - 2
12 = 2a
a = 6

-loga = log1/(b - 4)
loga^-1 = log1/(b - 4)
log1/a = log1/(b - 4)
1/a = 1/(b - 4)
a = b - 4
6 = b - 4
10 = b

logb = xloga
log10 = xlog6
1 = xlog6
6log6 = xlog6
x = 6

Titik-titik nya abaikan, anggap seperti spasi
