(2b)/(3)-5=3

((3a)/(5)+(2b)/(3))((3a)/(5)-(2b)/(3))= ?

((a)/(b))=((-2)/(3))^(5)+((-2)/(3))^(4) , find the value of ((a)/(b))^(-3)

If ((a)/(3)=1,b-(2)/(3))=((5)/(3),(1)/(3)), find the values of a and b.

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)]]

(3a-2b)^(3)+(2b-5c)^(3)+(5c-3a)^(3)

Evaluate : and write the answer in factors form : (3a- 2b)^(3) + (2b- 5c)^(3) + (5c- 3a) ^(3)

If a/2=b/3=c/5=(3a-5b+4c)/(K) then find the value of K.

Evaluate : (7)/(2a+3b)-(5)/(2a-3b)

If 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))] , then compute 3A-5B .
