Question

Sederhanakanlah

a.2 per 3 × 2log 64 - 1per2 × 2log 16
b. alog2x + 3(alogx -a log y)
c. alog a per √x -a log √ax
d. log √a + log √b-1per2 log ab

Answer 1

A.2/3 x 2 log 2⁶-1.2 x 2 log 2⁴ = 2/3 * 6- 1/2* 4 = 4- 2 = 2
b. a log 2x + 3 log x/y = 3 log 2x²/y
c. a log a/√x-a log √ax = a log  ( a/ √x × √ax ) = a log ( a / x√a ) dirasionalkan menjadi a log a√a/xa disederhanakan , a log √a/x

d. log √a +log√b - 1/2 log ab = log√ab -1/2 log ab = 1/2 log √ab/ab
