How do I simplify these equations?

12. 1/25 13. y to the power of 3. 14. 1/8. 15. x to the power of 10.

Step-by-step explanation:

12. The rule for multiplying exponents with the same base is to add the powers. 3 plus -5 is -2. 5 to the power -2 needs to be written 1 over, so one is the numerator and the power changes from negative to a positive. 1/5 to the power of 2, simplify 4 to the power of 2 to 25 (5 times 5). 1/25.

13. It is the same thing add 8 plus -5, and you will get 3, so it will be y to the power of 3.

14. For division, you have to subtract the power or the exponent 5 minus 8 is -3. So, you have 2 to the power of -3, as in number 12, you write 1/2 to the power of 3. Simplify 2 to the power or 3 by ding 2 times 2 times 2. You get 1/8/

15. subtract 15 minus 10 and the quotient and simplified version is x to the power of 10. Hope this helps!

the answer will be

r and t.

both are 64 degrees.
