Q4(5X)power a+4(5X)power 1 soltn; add the powers since we are multipling same bases,indice=(5X)power a+4+1=(5X)power a+5
x^(-1/3) * y^(1/3) - x^(2/3) * y^(-2/3)
= (y^1/3 / x^1/3) * (x^2/3 / y^2/3)
= (x^2/3 y^1/3) / (x^1/3 y^2/3)
= x^1/3 / y^1/3
= (x/y)^(1/3)
= (y^1/3 / x^1/3) * (x^2/3 / y^2/3)
= (x^2/3 y^1/3) / (x^1/3 y^2/3)
= x^1/3 / y^1/3
= (x/y)^(1/3)
