Question

solve this question plz..

Answer 1

q28) log ( a.a b.b.b. c^-4)^1/12
= 1/12 log ( a.a b.b.b .c ^-4)

1/12 ( log a.a + log b.b.b. + log c^-4)

1/12( 2log a + 3 log b -4 logc)

1/6 log a + 1/4 log b - 1/3 logic


q29) log √27x /x^3

= log √27x - log x^3

= 1/2 log 27x -3 logx

= 1/2 log 27 + 1/2 log x - 3 log x

= 1/2 log 27 - 5/2 logx
= 1/2 log 3.3.3 - 5/2 logx
= 3/2 log 3 - 5/2 logx
= 1/2 ( 3log 3 - 5 logx)
