Which of the following functions is reduced what will be the exponent on the M 27mn^3/51m^6n

When you divide a base with an exponent by a base with an exponent, you subtract the exponents together. (But you can only combine exponents when the bases are the same)

For example:

   (You can't combine them as they have different bases of x and y)

When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.

For example:

or

or    

     You can simplify the whole fraction or just "m" since you need to find the exponent of "m". I will simplify the whole fraction.

     Make all the exponents positive

   So the exponent of m = 5, your answer is the 3rd option

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

step-by-step explanation:

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
