hiw to find cube root of a number? step by step please
Answers
Answer:
Cube root is the inverse process of calculating the cube of a number. It is denoted by the symbol ‘∛’. Let us see some examples here now.
To find the cube root of a number 27, we want a number which when multiplied thrice with itself shall give 27. We can write,
27 = 3 × 3× 3 = 33
Taking cubic root on both the sides;
or ∛27 = ∛33
Therefore, the cube-root of 27 is 3.
Please note that we will only consider the positive values cube roots of the natural numbers.
Answer:
To find the cube root of a number, you want to find some number that when multiplied by itself twice gives you the original number. In other words, to find the cube root of 8, you want to find the number that when multiplied by itself twice gives you 8. The cube root of 8, then, is 2, because 2 × 2 × 2 = 8. Notice that the symbol for cube root is the radical sign with a small three (called the index) above and to the left equation. Other roots are defined similarly and identified by the index given. (In square root, an index of two is understood and usually not written.) Following is a list of the first eleven perfect (whole number) cube roots.
