321
It is 32 :]
32 add 16 = 48
4 + 4 + 32 = 40
289
To find what you need to add to 32 to reach 100, you would subtract 32 from 100. This gives you 68. Therefore, you need to add 68 to 32 to reach 100.
32 32
97
96 is the answer because 32 + 32 = 64 then add another 32 it = 96 :)
36
2893 = 289 x 289 x 289 = 24137569
289 = 289/1
the answer is 409. you add all number together then divide them by 4. it would give you 1636. 334+134+289+879=1636 and divide by 4 will give you 409
