What is the cube root for 125?

What is the cube root for 125?

The cube root of 125 is the number which when multiplied by itself three times gives the product as 125. Since 125 can be expressed as 5 × 5 × 5. Therefore, the cube root of 125 = ∛(5 × 5 × 5) = 5.

Is a cube root Plus or minus?

Unlike a square root, the result of a cube root can be any real number: positive, negative, or zero. Also different from a square root is the domain restriction on the radicand: the radicand of a cube root can be negative while still achieving a real result for the cube root.

Is a cube root a function?

y=a3√x−h+k, where a,h,k are real numbers. a,h, and k play the same roles as they did for square root functions. However, we can take the cube root of any real number, including negative numbers; therefore, cube root functions will be defined for all values of x….Example 1.

Does the cube root function decrease?

It is decreasing on ∞, 0 and increasing on 0, ∞). 5. Cube Function: Domain: ∞,∞ Its ‐intercept is 0,0 . It is increasing on ∞,∞ .

What is the parent equation for the cube root function?

Let’s now study the parent function of cube root functions. Similar to the square root function, its parent function is expressed as y = ∛x. The graph shows that the parent function has a domain and range of (-∞, ∞).

Does a cube root have two answers?

2 Answers. −2 isn’t a cube root of 8. If you’re sure your book’s claiming it is, then that’s a typo. You’re right that numbers only have one cube root, as long as we’re sticking to real numbers.

What should be divided by 53 to 40 to make it a perfect cube?

If we divided the number by 5, then the prime factorisation of the quotient will not contain 5. Hence the smallest number by which 53240 should be divided to make it a perfect cube is 5. The perfect cube in that case is=10648.

Is 9000 a perfect cube?

No , 9000 is not a perfect cube. PERFECT CUBE: A perfect cube is a number that is cube of an integer. so here in the given question 2 is cubed and 5 is cubed but 3 is not cubed. So 9000 isn’t a perfect cube.

What is the cube root of 10648 by prime factorization method?

Complete step by step solution: Hence the cube root of 10648 is 22.

IS 128 a perfect cube?

Grouping the prime factors of 128 into triples, we are left over with 2 as ungrouped factor. ∴ 128 is not a perfect cube.

Is 9261 a cube root?
