Example

a ^ 0 = 1

2 ^ 0 = 1

a ^ 1 = a

17 ^ 1 = 17

sqrt(a) = a ^ (1/2)

sqrt(4) = 4 ^ (1/2)

root(a, n) = a ^ (1/n)

root(27, 3) = 27 ^ (1/3)

a ^ (- m) = 1/(a ^ m)

9 ^ - 2 = 1/(9 ^ 2)

(a/b) ^ m = (a ^ m)/(b ^ m)

(5/6) ^ 2 = (5 ^ 2)/(6 ^ 2)

a ^ m * a ^ n = a ^ (m + n)

5 ^ 2 * 5 ^ 4 = 5 ^ (2 + 4)

(a ^ m)/(a ^ n) = a ^ (m - n)

(4 ^ 5)/(4 ^ 3) = 4 ^ (5 - 3)

(a ^ m) ^ n = a ^ (mn)

(2 ^ 5) ^ 3 = 2 ^ (5 * 3)

a ^ n * b ^ n = (ab) ^ n

2 ^ 5 * 3 ^ 5 = (2 * 3) ^ 5

a ^ (m/n) = root(a ^ m, n)

81 ^ (3/2) = root(81 ^ 3, 2)

(a/b) ^ (- n) = (b/a) ^ n

(3/4) ^ - 2 = (4/3) ^ 2

Algebra Formulas

(a + b) ^ 2 = a ^ 2 + 2ab + b ^ 2

(a - b) ^ 2 = a ^ 2 - 2ab + b ^ 2

a ^ 2 + b ^ 2 = (a + b) ^ 2 - 2ab

a ^ 2 - b ^ 2 = (a + b)(a - b)

(a - b) ^ 2 = (a - b) ^ 2 + 4ab

(a - b) ^ 2 = (a - b) ^ 2 - 2ab

a ^ 2 + b ^ 2 = (a - b) ^ 2 + 2ab

2(a ^ 2 + b ^ 2) = (a - b) ^ 2 + (a - b) ^ 2

2(a ^ 2 + b ^ 2) =(a+b)^ 2 +

4ab = (a + b) ^ 2 - (a - b) ^ 2

ab = ((a + b)/2) ^ 2 - ((a - b)/2) ^ 2

(a + b) ^ 3 = a ^ 3 + 3a ^ 2 * b + 3a * b ^ 2 + b ^ 3

(a + b) ^ 3 = a ^ 3 + b ^ 3 + 3ab(a + b)

(a - b) ^ 3 = a ^ 3 - 3a ^ 2 * b + 3a * b ^ 2 - b ^ 3

(a - b) ^ 3 = a ^ 3 - b ^ 3 - 3ab(a - b)

( a - b ^ 3 = (a + b)(a ^ 2 - ab + b ^ 2)

a ^ 3 + b ^ 3 = (a + b) ^ 3 - 3ab(a + b)

a ^ 3 - b ^ 3 = (a - b)(a ^ 2 + ab + b ^ 2)

a ^ 3 - b ^ 3 = (a - b) ^ 3 + 3ab(a - b)

(a + b + c) ^ 2 = (a ^ 2 + b ^ 2 + c ^ 2) + 2(ab + bc + ca)

(a ^ 2 + b ^ 2 + c ^ 2) = (a + b + c) ^ 2 - 2(ab + bc + ca)

2(ab + bc + ca) =(a+b+c)^ 2 -;(a^ 2 +b^ 2 +c^ 2 )

(a + b + c) ^ 2 = a ^ 3 + b ^ 3 + c ^ 3 + 3(a' + b)(b + c)(c + a)

a³+b³ + c³-3abc = (a+b+c)(a² + b²+c² ab - bc - ca)

a3 + b3 + c3 - 3abc = (a+b+c){(a - b)² + (b - c)² + (ca)2}

(x + a)(x + b) = x ^ 2 + (a + b) * x + ab

(x + a)(x - b) = x ^ 2 + (a - b) * x - ab

(x - a)(x - b) =x^ 2 -(a-a x+ab

(x + p)(x + q)(x + r) = x ^ 2 + (p + q + r) * x ^ 2 + (pq + qr + rp) * x + pqr

bc(b - c) + ca(c - a) + ab(a - b) = - (b - c) * (c - a)(a - b)
