To compare the fractions 3/16 and 3/19, we need to find a common denominator.

The least common multiple of 16 and 19 is 304.

So, we can convert 3/16 to an equivalent fraction with a denominator of 304:

3/16 = (3/16) * (19/19) = 57/304

And we can convert 3/19 to an equivalent fraction with a denominator of 304:

3/19 = (3/19) * (16/16) = 48/304

Now we can see that 57/304 is greater than 48/304, so:

3/16 > 3/19

Solution:
(x^3y^-2y)^-2(5x^-5)^-2
(x^3y^-2y)^-2(5x^-5)^-2 = (x^3 / y^4)^-2 (1 / 5^2x^5)^-2
(y^4 / x^3)^2 (5^2x^5 / 1)^2
y^8 / x^6 * 25x^10
25y^8 / x^-6
= x^6 / 25y^8

Aspirin should not be given to children. Epidemiological research has shown an association between the development of Reye's Syndrome and the use of aspirin (a salicylate compound) for treating the symptoms of influenza-like illnesses, chicken pox, colds, etc.

The U.S. Surgeon General, the Food and Drug Administration, the Centers for Disease Control and Prevention, and the American Academy of Pediatrics recommend that aspirin and combination products containing aspirin not be given to children under 19 years of age during episodes of fever-causing illnesses.
