Answer 2

1a) = ³log(27×6/2) = ³log81 = ³log3⁴ = 4
b) = log(10x2/4 x 20) = log(400/4) = log10² = 2
c) = ³^²log3² + 0 - 1 = 2/2 ³log3 -1
= 1 - 1 = 0
d) = 7'log7^-2 x 5^2'log5
= -2 x ½ = -1

2a) log 0,6 = log(6/10) = log2 + log 3 - log10
= 0,301 + 0,4771 - 1 = - 0,2219
b) log 60 = log(2x3x10)
= 0,301 + 0,4771 + 1
= 1,7781
c) log135 = log(3³ x 5) = 3log3 + log5
= 3x0,4771 + 0,6989
= 2,1302
d) log0,45 = log(45/100) = log(3²x5/10²)
= 2x0,4771 + 0,6989 - 2
= - 0,3469
