7 to the 6th power divided by 7 to the -3rd power = 40,359,862.8
Set the equation equal to 0: 7h - 2 - 51 = 0 add -2 and -51 to both sides: 7h = 53 Divide h = 53/7

7 to the sixth power in exponent form is 76
5x+3y = 51 y = 10x-8 Substituting the bottom equation into the top equation: 5x+3(10x-8) = 51 5x+30x-24 = 51 5x+30x = 51+24 35x = 75 Divide both sides by 35 to find the value of x: x = 75/35 = 15/7 in its lowest terms. Substitute the value of x into the original equations to find the value of y: So: x = 15/7 and y = 94/7

751 isn't a question. It's just a number. The number is aproximately 12,589,255,300,000,000,000,000,000,000,000,000,000,000,000 (rounded)
7 x 51 = 357

51/21 = 17/7 = 23/7
51 minus 27 3/7 = 23 4/7
-58
51 > 0. Since the sum 14 is positive, the factors of 51 are both positive. The problem is that 51 = 3*17 and 3 + 17 = 20 ≠ 14. But we are lucky that 14 = 7 + 7. So wee can use the difference of the squares such as (7 - A)(7 + A) = 49 - A2 = 51, where -A2 = 2 = -(i√2)2 . Thus, the numbers are 7 - i√2 and 7 + i√2. or algebraically, x + y = 14; y = 14 - x xy = 51 x(14 - x) = 51 -x2 +14x = 51 x2 -14x = -51 x2 -14x + 72 = -51 + 49 (x - 7)2 = -2 x - 7 = ± √-2 x = 7 ± i√2
