(1120)/(2^(2)5^(7)+5)

Simplify: ((sqrt(2))/(5))^(8)-:((sqrt(2))/(5))^(13) (ii) ((5^(-1)x7^(2))/(5^(2)x7^(-7)))^((1)/(2))x((5^(-2)x7^(3))/(5^(3)x7^(-5)))^(-(5)/(2))

Simplify ((5^(-1)*7^(2))/(5^(2)*7^(-4)))^((7)/(2))*((5^(-2)*7^(3))/(5^(3)*7^(-5)))^(-(5)/(2))

((5^(-1)xx7^(2))/(5^(2)xx7^(-4)))^((7)/(2))xx((5^(-2)xx7^(3))/(5^(3)xx7^(-5)))^(-(5)/(2))

Simplify: ((5^(-3)xx7^(4))/(7^(-2)xx5^(-6)))^((5)/(2))xx((5^(-3)xx7^(-3))/(7^(5)xx5^(2)))^((3)/(2))

Simplify: ((5^(-3)xx7^(4))/(7^(-2)xx5^(-6)))^((5)/(2))xx((5^(-3)xx7^(-3))/(7^(5)xx5^(2)))^((3)/(2))

Evaluate the following limit: (lim)_(x rarr a)(x^(5/7)-a^(5/7))/(x^(2/7)-a^(2/7))

[((2)/(7))^(3)]^(5)=((2)/(7))^(8)

A=[[(2)/(3),1,(5)/(3)(1)/(3),(2)/(3),(4)/(3)(7)/(3),2,(2)/(3)]] and B=[[(2)/(5),(3)/(5),1(1)/(5),(2)/(5),(4)/(5)(7)/(5),(6)/(5),(2)/(5)]]
