Answer:

Step-by-step explanation:

[tex]a = b^{c}[/tex]   ------------(I)

Plug in b = [tex]c^{a}[/tex]

(I) ---> [tex]a = (c^{a})^{c}= \ c^{a*c} = \ c^{ac}[/tex]    -----------(II)

Plug in c = [tex]a^{b}[/tex]

(II) ----->

 [tex]a = (a^{b})^{ac} \\\\a = a^{ac*b}\\\\a = a^{abc}[/tex]

Both sides base are same. So, compare the powers

1 = abc

abc = 1

Hence proved
