Simplify : (25\ x\ a^(-4))/(5^(-3)\ x\ 10\ x\ a^(-8)) (ii) (3^(-5)\ x\ 10^(-5)\ x\ 125)/(5^(-7)\ x\ 6^(-5))

If x + (2)/(3 + (4)/(5+(7)/(6)))=10 , then the value of x is

Simplify : (25\ "x"\ a^(-4))/(5^(-3)\ "x"\ 10\ "x"\ a^(-8)) (ii) (3^(-5)\ "x"\ 10^(-5)\ "x"\ 125)/(5^(-7)\ "x"\ 6^(-5))

lim_ (x rarr oo) ((x + 2) ^ (10) + (x + 4) ^ (10) ++ (x + 20) ^ (10)) / (x ^ (10) +1) =

Solve: 7(x +4) = 4(x + 10)

Solve for x: (x-4)/(x-5)+(x-6)/(x-7)=10/3; x!=5,7
