===============================================

Explanation:

For the first expression, we use the rule that . We add the exponents when multiplying exponentials of the same base. So,

-----------

In the second expression, we can expand out into . The coefficients 2 and 2 multiply to 2*2 = 4 as the final coefficient. The y terms multiply to . So overall, that's how

-----------

We use the same idea for the third expression. We'll have two copies of y/4 multiplied together to end up with . We have in the numerator and 16 in the denominator.

-----------

For the fourth expression, we can use the rule that . In other words, if we raised to some other exponent c, then it's the same as writing . We multiply the exponents.

The exponents in this case are 3 and 3 which multiply to 9. The 2 is then tacked up front to get
