Question

please answer question no. 14.(ii)

Answer 1

a raise to x = b
b raise to y= c
hence a raise to x raise to y=c
${a}^{ {x}^{y} } = {a}^{xy}$
similarly c raise to z = a
hence
a raise to xy = c
a raise to xyz= c raise to z as shown earlier
given
${a}^{xyz} = a$
a raise to xyz is only true when xyz =1
