Answer:

Hey buddy here is your answer

(i)15  (ii)3

Explanation:

(i) ㏒₁₀(7x-5)=2                   (ii) a²/bc+b²/ca+c²/ab = (a³+b³+c³)/abc

⇒7x-5=10²=100                     If a+b+c=0, a³+b³+c³=3abc

⇒7x=105                            ⇒(a³+b³+c³)/abc = 3abc/abc

⇒x=15                                  =3
