Each real number has exactly one cube root
WebThe Definition of Square and Cube Roots. A square root of a number is a number that when multiplied by itself yields the original number. For example, 4 is a square root of 16, because 42 = 16. Since (− 4)2 = 16, we can say that −4 is a square root of 16 as well. Every positive real number has two square roots, one positive and one negative. WebApr 28, 2024 · 5 Answers. f ( x) = x 2 ( x + 3) + 16 so only for x < − 3 can there be a real root. f ′ ( x) = 3 x ( x + 2) and for x < − 3 this is always positive. Hence there is only one …
