Question

hello

(ch2p2.2q4,5)

Plz explain in detail correctly step by step .

do give ans of both Qs.

​

Answer 1

Explanation:

4)

Given:

= log [ { (9 / 8) / (27 / 32) } x 3 / 4) ]

= log [ (9 / 8) x (3 / 4) x (32 / 27) ]

= log 1

= 0

5)

log5((25^(1/4))/(625))

=log5(5^(1/2)) / 5^(4))

= log5(5^(1/2 - 4))

= log5(5^(-7/2))

= -7/2

Hope it helps u mark as brainliest please
