Nilai 5log 100 - 5log 4 + 5log 5

5log 100 - 5log 4 + 5log 5
=(5log 100 - 5log 4) + 5log 5
= 5log (100/4) + 5log5
= 5log 25 + 5log 5
= 5log (25.5)
= 5log 125
= 5^y = 125
= 5^y = 5³
= y = 3
semoga membantu :)

⚔ Soal : 5log 100 - 5log 4 + 5log 5

⚔ Penyelesaian :

→ 5log (10²) - 5log 4 + 5log 5

→ (5x2) + log [4^(-5)] + log [10^5]

→ 10 + log [4^(-5) + 5^5]

→ 10 + log [(5^5) / (4^5)]

→ 10 + log [5/2²]^5

→ 10 + 5log [5/2²]

→ 10 + 5log [5/4]

→ 10,48455
