Question

Can someone help please

Answer 1

11). A perfect square does not always have to be even. A perfect square is when a number divides into a number that can be multiplied by itself to get the bigger "perfect square" number.

15) Irrational. The product "Answer" would just be adding onto the rational number. Like 5 x √3 would just be 5√3.

16) No they dont. √100-64 would be the value of √36 (6). √100 (10) - √64 (8) = 2

Answer 2

15) it is irrational, because if you do a rational times a irrational you must get something with decimals
16)No, because /100 -64 is /36 and is 6 and /100 - /64 is 10 - 8 is 2

I'm not 100% sure thou h
