... Remarks: If any argument is nonnumeric, GCD returns the #VALUE! error value. If any argument is less than zero, GCD returns the #NUM! error value. One divides any value evenly. A prime number has only itself and one as even divisors. Examples: GCD(5, 2) equals 1 GCD(24, 36) equals 12 GCD(7, 1) equal ...

... Now we would like to generalise the concept of square root and cube root to higher order. If a number to the nth power (where n is an integer greater than 1) is equal to a, then this number is called the nth root of a. In other words, if x n = a , then x is called the nth root of a. The computation ...

... Suppose that i ϵ R. Then we know that i is greater than zero, equal to zero, or less than zero. If we take i to be greater than zero, then i2 = i ∙ i > 0 since the product of two positive numbers is positive. That is, -1 > 0 which is false. Therefore, i cannot greater than 0. Similar contradictions ...

... Consider the polynomial equation x2 + 3x + 2 = 0. Since x2 + 3x + 2 = (x + 1)(x + 2), the two solutions are x = −1 and x = −2. Unfortunately not all such equations have (real number) solutions. For example, since x2 > 0 for all x ∈ R, x2 + 1 > 0 + 1 = 1 > 0 for all x ∈ R ⇒ x2 6= −1 for all x ∈ R. To ...
