⁵log 10 + ⁵log 50 - ⁵log 4
= ⁵log (10 . 50/4)
= ⁵log 125
= ⁵log 5³
= 3 . ⁵log 5
= 3

[tex] {}^{5} log(10) + {}^{5} log(50) - {}^{5} log(4) \\ = {}^{5} log( \frac{10 \times 50}{4} ) \\ = {}^{5} log( \frac{5 \times 50}{2} ) \\ = {}^{5} log(5 \times 25) \\ = {}^{5} log(125) \\ = {}^{5} log(5 {}^{3} ) \\ = 3. {}^{5} log(5) \\ = 3 \times 1 \\ = 3[/tex]
