how come I get the feeling that the -2, 8, and -3 are all exponents ?

is this what you mean ?

$\frac{y^{-2}}{y^8} \cdot \frac{1}{y^{-3}}$

For fractions, when multiplying, you mupltiply the numerator with the numerator and the denominator with the denominator.

$\left(\frac{y^{-2}}{y^8}\right)\left(\frac{1}{y^{-3}}\right)$

Or

$\left(\frac{y-2}{8y}\right)\left(\frac{1}{y-3}\right)$

Or

Something else? :confused:

Those may be exponents,....
The Prof. wrote the problem out exactly like that. They may be exponents, I am not sure, thanks for the replys.
