`(-3/5)^-4(-2/5)^2`

(-(3)/(5))^(-4)xx(-(2)/(5))^(2)

(3)/(12) of (((2)/(5)+(4)/(15)))/(((3)/(5)-(2)/(5)))= ?

The sum of the infinite series,1^(2)-(2^(2))/(5)+(3^(2))/(5^(2))-(4^(2))/(5^(3))+(5^(2))/(5^(4))......is

Evaluate: (i) ((5)/(9)) ^(-2) xx ((3)/(5)) ^(-3) xx ((3)/(5)) ^(0) (ii) ((-3)/(5)) ^(-4) xx ((-2)/(5))^(2) (iii) ((-2)/(3)) ^(-3) xx ((-2)/(3)) ^(-2)

Using commutativity and associativity of addition of ration of numbers,express each of the following as a rational number: (4)/(3)+(-4)/(5)+(-2)/(3)+(7)/(5)-2

If A=[(2)/(3)1(5)/(3)(1)/(3)(2)/(3)(4)/(3)(7)/(3)2(2)/(3)] and B=[(2)/(3)(2)/(5)1(1)/(5)(2)/(5)(4)/(5)(4)/(5)(7)/(3)(6)/(5)(2)/(5)], then compute 3A_(-)=5B

(3)/(5)+(4)/(5^(2))+(3)/(5^(3))+(4)/(5^(4))+... to 2n terms

(4)/(5)times((-2)/(3))-(2)/(5)times(1)/(3)+(3)/(5)times(4)/(5)=

Simplify: (2)/(3)m-(4)/(5)n+(3)/(5)p+(-(3)/(4)m-(5)/(2)n+(2)/(3)p)+((5)/(2)m+(3)/(4)p-(5)/(6)n)
