Answer:

False


\frac{57 {x}^(5) }{19x^(3) } = 3 {x}^(2)

Answer:

True.

Explanation:

The given expression is


(57x^(5) )/(19x^(2) )

This expression has to be restricted, because when
x=0, the expression is undefined.

Remember, when a fraction has a null denominator, that means the fraction is infinite or undetermined.

So, in this case, let's replace for
x=0


(57x^(5) )/(19x^(2) )=(57(0)^(5) )/(19(0)^(2) )=(0)/(0)

Which is an undetermined expression.

Therefore, the asnwer is true.
