Does a^3 × b^3 = 3^3 can't be easily solved with fraction 1/3. To be fair. The powers wont be equal value to digit?

    a³ x b³ = 3³

    (ab)³ = 3³

    ab = 3

    Put a = 1, b = 3 (or) a = 3, b = 1

    (a^3)(b^3)=3^3

    =>

    (ab)^3=3^3

    =>

    ab=3

    =>

    b=3/a

    For every given "a" there is one "b"correspond-

    ing to it. Thus there are infinitely many (a,b) in R, except a=0 or b=0, satisfying the given equation. e.g. if a=1, then b=3=>(1,3) is a solut-

    ion.

    (a^3)(b^3) = (ab)^3 = 3^3...(1). (1) holds for ab = 3.

    a³×b³ = 3³

    (ab)³ = 3³

    ab = ∛3³ = 3

    Suppose (a,b) = (⅓,9).

    a³×b³ = (⅓)³×9³ = (1/27)×729 = 27 = 3³

    What are you talking about? The left would just be (ab)^3 using the distributive property. Or, if you leave the problem as it is, if a or b = 1/3:

    (1/3)^3 × b^3 = 3^3

    3^(-3) × b^3 = 3^3

    b^3 = 3^3 / 3^(-3)

    b^3 = 3^(3 + 3)

    b^3 = 3^6

    b = (3^6)^(1/3) = 3^(6 × 1/3) = 3^2 = 9.

    As long as ab = 3, 1/3 works fine.

    Your question make no sense. Please be articulate and repost.

    I can't understand your problem, especially the part about "solved by fraction 1/3".  One possible solution is a = 1, b = 3.  Why don't you like that?

    all you have is ( ab)³ = 3³ ===> ab = 3
