Answer 1

Penjelasan dengan langkah-langkah:

no. 1

log2 + log18 - log6 + log5 - log3

= log2 + log5 + log18 - (log6 + log3)

= log2 + log5 + log18 - log(6×3)

= log2 + log5 + log18 - log18

= log(2×5)

= log10

= 1

jawqbannya : C

no. 2

⁵log150 - ⁵log24 + ⁵log4

= ⁵log150 + ⁵log4 - ⁵log24

= ⁵log(150×4/24)

= ⁵log25

= ⁵log5²

= 2

jawabannya : B

no. 3

log30 - 1/⁴⁸log10 + 1/¹⁶log10

= log30 - log48 + log16

= log30 + log16 - log48

= log(30×16/48)

= log10

= 1

jawabannya : B

no. 4

[²log√5 + 2.⁴log5] / [²log3. ³log5]

= [(1/2).²log5 + 2.²^²log5] / ²log5

= [(1/2).²log5 + (2/2).²log5] / ²log5

= [(1/2).²log5 + ²log5] / ²log5

= (3/2).²log5 / ²log5

= 3/2

jawabannya : C

no. 5

ᵖlog81 - 2.ᵖlog27 + ᵖlog27 + ᵖlog243 = 6

ᵖlog81 - ᵖlog27 + ᵖlog243 = 6

ᵖlog81 + ᵖlog243 - ᵖlog27 = 6

ᵖlog(81×243/27) = 6

ᵖlog729 = 6

729 = p⁶

3⁶ = p⁶

p = 3

jawabannya : C
