Laws of Exponents part 2

The law of exponent is when you multiply an exponent with the same variable as it base such as v^2 * v^3. The product of the expression is v^2 +3=v^5. When you divide exponent with the same variable its base such as n^7/n^3, the quotient of the expression is n^7-3. which makes the answer n^4. So do you see that in law of exponents when you are multiply u have to have the same variable and the exponent you have add. When you divide in the laws of exponents you have to have the same exponent and then you subtract the exponents.
