Prove that `(81/16)^(-3/4)xx{(25/9)^(-3/2)-:(5/2)^(-3)}=1`

Simplify (81/16)^(-3/4)xx[(25/9)^(-3/2)+(5/2)^3]

Prove that ((81)/(16))^(-(4)/(4))xx{((25)/(9))^(-(3)/(2))-:((5)/(2))^(-3)}=1

Simplify: ((81)/(16))^(-3/4)*[((25)/9)^(-3/2)-:(5/2)^(-3)]

Simplify: ((81)/(16))^(-3/4)*[((25)/9)^(-3/2)-:(5/2)^(-3)]

prove that ((81)/(16))^(-(4)/(4))*{((25)/(9))^(-(3)/(2))-:((5)/(2))^(-3)}=1

prove that ((81)/(16))^(-(4)/(4))*{((25)/(9))^(-(3)/(2))+((5)/(2))^(-3)}=1

simplify :((81)/(16))^(-(3)/(4))xx[((25)/(9))^(-(3)/(2))-:((5)/(2))^(-3)

Simplify: ((81)/(16))^(-(3)/(4))x[((25)/(9))^(-(3)/(2))-:((5)/(2))^(-3)]
