solve the following problem
Answers
Answer:
5)In short, the multiplicative identity is the number 1, because for any other number x, 1*x = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

8) -20+20=0
9) 34 1⁄3
10) 9x+9y
11) 121a - 121b
12) answer for this question is in the attachment ☺️☺️
13)−xy-9x+10y+90
hope my all the answers helped you!!☺️☺️
Answer:
5. x⁰ = 1
6.100⁰ = 1
7. 9² = 81
8. -20+20 = 0
9. 412 ÷ 4 = 103
10. 9(x + y) = 9x + 9y
11. 121(a - b) = 121a - 121b
12. (4 - x)(5 - y)
= 4(5 - y) - x(5 - y)
= 20 - 4y - 5x + xy
13. (9 + y)(10 - x)
= 9(10 - x) + y(10 - x)
= 90 - 9x + 10y - xy
