Log5+log4-log2+log10 = ?? mohon bantuannya ya kak

Log5 + log4 – log2 + log10 =
= log (5*4) – log2 + log10
= log 20 – log2 + log10
= log (20/2) + log10
= log 10 + log 10
= 1 + 1
= 2

ataupun

log5 + log4 – log2 + log10 =
= log (5*4) – log2 + log10
= log 20 – log2 + log10
= log (20/2) + log10
= log 10 + log 10
= log (10*10)
= log 100
= 2

Semoga berguna. Terimakasih.
