Simplify 5 to the 22 power over 5 to the fourth power

Step-by-step explanation:

When you have a problem that looks like that one does, namely:

that's an example of division of exponents.  The 5's are called the bases.  The rule is if you are dividing like bases (which we are) subtract the lower exponent from the upper exponent and that difference becomes the new power on the base.

Our exponents are 22 on top and 5 on the  bottom, so 22 - 5 = 17

17 is the new exponent on the 5, thus our simplification of this is

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
