The cubic root of 56 is approximately 3.7797631195.
To find the cubic root of 56, we can express it as:
∛(56)
However, 56 is not a perfect cube, so we cannot simplify it further. Hence, the cubic root of 56 remains as:
∛(56)
To find the cubic root of 56, you can use either a calculator or manual calculations. Here's how you can find the answer manually:
1. Start by factoring 56 into its prime factors. Here, 56 can be written as 2 × 2 × 2 × 7.
2. Group the prime factors into triples, with each triple consisting of three identical factors that can be taken out as a cubic root. In this case, we have one group of three 2's (2 × 2 × 2 = 8) and no groups of three 7's.
3. Write the result of the grouped prime factors and any remaining factors inside the cubic root symbol. In this case, the cubic root of 56 can be written as:
∛( 8 × 7 )
( 2 )
4. Simplify the cubic root expression. The cubic root of 8 is equal to 2, which leaves us with:
∛( 2 × 7 )
5. Multiply the numbers inside the cubic root. Here, 2 × 7 is equal to 14.
Therefore, the cubic root of 56 is ∛14.
