Question

integration of e to the power x^2​

Answer 1

x2 = 25, so x = 5 x = 5 or x = −5

(x−5)2 = x2 − 25 = (x−5)(x−5) = x2 − 10x + 25

√(x2+y2) = x + y √(x2+y2) is as far as we can go

x2x4 = x8 = x6 (add exponents)

(x2)4 = x6 = x8 (multiply exponents)

2x-1 = 1/(2x) = 2/x

−52 = 25 = −25 (do exponent before minus)

(−5)2 = −25 = +25 (do brackets before exponent)

5½ = 1/52 = √5

log(a+b) = log(a) + log(b) log(a+b) is as far as we can go

x(a/b) = xa/xb = xa/b

x−(5+a) = x−5+a = x−5−a
