Question

Please help!!!! There are exclusions that make the expression 57x^5/19x^2 undefined. true false?

Answer 1

Answer:

False

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

Answer 2

Answer:

True.

Step-by-step explanation:

The given expression is

$\frac{57x^{5} }{19x^{2} }$

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 $x=0$

$\frac{57x^{5} }{19x^{2} }=\frac{57(0)^{5} }{19(0)^{2} }=\frac{0}{0}$

Which is an undetermined expression.

Therefore, the asnwer is true.
