The answers for number 9 are 4^2 and 7^12 respectively. Number 10 is 1/125

Step-by-step explanation:

For the 4^4/4^2 You can use the properties of exponents to solve. When you are dividing exponents with the same base, you can subtract the powers. So the power 4 minus the power 2 gives you 2, so your answer is 4^2.

For the 7^4*7^8 you can also use properties of exponents. When you are multiplying exponents, you can add the powers. So 4+8=12. Your answer would be 7^12

For 5^-3, this is also a power of exponents, but different. When you are given something to the negative exponent, you take the inverse, and keep the power. For your problem it would become 5^-3=1/5^3. Solving 5^3 gives 125, so your answer would be 1/125
