Divide y^7/y^5. Write the quotient as one power. The variable is not equal to zero.


If it requires 10^4 silkworms to produce enough silk to make a scarf in a given amount of time, but it requires 10^19 silkworms to produce enough silk to make a sheet in the same amount of time. How many times more silkworms are needed for the sheet than the scarf? Hint: Divide number of silkworms to make a sheet by the number of silkworms to make a scarf.


Simplify: (6^-4)^6


Simplify: 13^4 x 14^4


When multiplying powers with the same base, keep the base and multiply the exponents. Explain, in complete sentences, whether this statement is true or false, and why.

Answer :

When dividing variables, subtract the powers. So for a 7-5 is 2 so the answer would be y^2. When multiplying variables, add the powers. When raising a power to another power, multiply them.
