To increase 28 to 96, you need to add 68. This can be calculated by subtracting 28 from 96, which equals 68. Therefore, increasing 28 by 68 results in 96.
square-root of 68 times square-root of 68 = 68 (square-root of any number) squared is that number
19 and 34. Let the two numbers be x and y; then: x - y = 15 x + y = 53 Adding the two equations gives: 2x = 68 → x = 34 Substituting for x in the second gives: 34 + y = 53 → y = 19 Checking by substituting for x and y in the first gives: 34 - 19 = 15 as required.
Don't see any "following" and this I's guessing is what you want? 113-(-68)^.5 = 113-((-1)(68))^.5 = 113-(68)^.5 (-1)^.5 = 113-i(68)^.5
