Calculate log 4 Logsquareroot 3 i taniSolutionSolutions a

Calculate: log (-4) Log(squareroot 3 - i). tan(i).

Solution

Solutions :

( a ) log( - 4 )

Steps :

log₁₀( - 4 )

log_a(b) ; b <0 is undefined

= undefined

( b ) log(3 - i )

Steps :

log₁₀(3 - i )

Factor - i + 3 :

- i + 3

Factor out common term - 1

= - ( i - 3 )

log₁₀(3 - i ) =  log₁₀(- ( - 3 + i ))
