Highlighted Questions below please: if you could explain how to answer them or give me the answers that would be great :))

Answer 1

Here is some to start you off.
Basically, you have to square root it.

10. Square root of 25 is 5 to t = 5.

11. k = 22

12. z = 16 because 16x16=256 then 256 - 256 is 0.

13. You do the opposite to get your answer. -50 + 14 = -36. Square root of 36 is 6. d = 6.
