Question

k

Answer 1

\[\frac{ x^{5} }{x ^{3} } = \frac{ 16x^{3} }{ x^{3} }\]

Answer 2

\[x^{5} = 16x ^{3}\]

Answer 3

consider the both equation

dividing both sies by x3 gives

i.e
and hence
however, as well as these two solutions of x = 4 and x = -4 there is another value for x that satisfies the original equation. what is this 3rd solution tot he original equation?
