Cube root of polynomial
WebHere a 1, a 2 are coefficients and the exponents of both the terms are 1, 5 respectively. Both being whole numbers. Now consider 3. We know that any number raised to zero is equal to 1. ⇒ x 0 = 1. ⇒ 3 = 3 × 1. = 3 x 0. 3 x 0 satisfies all the criteria for an expression to be a polynomial. Hence, 3 = 3 x 0 is a single term polynomial, also ... WebCube root of number is a value which when multiplied by itself thrice or three times produces the original value. For example, the cube root of 27, denoted as 3 √27, is 3, …
