simplist form without negative exponents

Question

is this correct for my answer

 

 

(ax)^2    =     1/(ax)^2    =     1/a^2x^2

 

 

 

 

how do I simplfy this problem  assuming the solutio is undefined,

 

 

     ( a^2b^3)  ^2                            The parentheses goes around the denomator, c,

          c

Answer 1

(ax)^2 = a^2 x^2

 

(a^2 b^3/c)^2

= (a^2)^2 (b^3)^2 / (c)^2

= a^4 b^6/c^2
