Step-by-step explanation:
24) 2 log x - 3 log y + 4 log z
= log x square - log y cube + log z power 4
= log x square + log z power 4 - log y cube
= log ( x square. z power 4 ) - log y cube [ ∵ log to the base of xy= log to the base of x + log to the base of y ]
= log ( x square. z power 4 / y cube ) is the answer. [ ∵log to the base a of x/y = log to the base of x - log to the base of y ]
25) Log to the base 2 of 0.25
Let log to the base 2 of 0.25 = x
⇒ ㏒ to the base 2 of ( 0.5) square = x
⇒square ㏒ to the base 2 of ( 0.5) = x
⇒ (0.5) square = x square
⇒ 2 is the answer.
