Serial Number | Algebraic Formula |
1 | (a + b)2 = a2 + b2 + 2ab |
2 | (a - b)2 = a2 + b2 - 2ab |
3 | (a + b)3 = a3 + b3 + 3ab2 + 3a2b |
4 | a3 + b3 = (a + b)3 - 3a2b - 3ab2 |
5 | (a - b)3 = a3- b3 - 3a2b + 3ab2 |
6 | a3- b3 = (a - b)3 + 3ab(a+b) |
7 | (a + b + c)2 = a2 + b2 + c2 + 2(ab + bc + ca) |
8 | (a + b)2 + (a - b)2 = 2(a2 + b2) |
9 | (a2- b2) = (a - b)(a + b) |
10 | (a3 + b3) = (a + b)(a2 - ab+ b2) |
11 | (a3 - b3) = (a - b)(a2 + b2 + ab) |
Serial Number | Exponential Formula |
1 | anam = an+m |
2 | (a.b)n = an. bn |
3 | a0 = 1 |
4 | (am)n = amn |
5 | am/n = n√am |
6 | a-m = 1/am |
7 | (am/an )= a(m-n) |
