Question

oblicz:
a)log1/2+log2
b)log₂16-log₄64
c)log₆72-log₆2
d)log₄3+log₄4/3
e)log₃27+log₄16

Answer 1

Odpowiedź:

a)  log1/2 + log2 = log(1/2 *2) = log1 = 0

b)  log₂16 - log₄64 = 4 - 3 = 1

c)  log₆72 - log₆2 = log₆(72/2) = log₆36 = 2

d)   log₄3 + log₄(4/3) = log₄(3  * 4/3) = log₄4 = 1

e)  log₃27 + log₄16 = 3 + 2  = 5

Answer 2

Odpowiedź:

a) log (1/2) +log 2= log (1/2*2)= log 1=0

b)

log ₂16- log ₄64=4-3=1

c)

log ₆72-log₆2= log ₆(72/2)=log₆36=2

d)

log ₄3+log ₄  (4/3)= log ₄( 3*4/3)= log ₄4=1

e)

log ₃27+log₄16=3+2=5
