In a science class students learn that friction is the resistance to motion when two objects rub together the students decide to desing an expirement at home to compare friction on a dry and icy surfaces which question is most beneficial for this type of investigastion

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
