The cube root of 9 is the number x such that x^3 = 9. What is the cube root of 9 with the answer of 3 as the base? The cube root of 5 is an irrational number, meaning it cannot be written as a/b where a and b integers and b is not 9. However, how does one prove this on paper? 9^(1/3) = 2.08008382305. Read this post to learn everything about the third root of 9. read more . elementary-number-theory proof-writing irrational-numbers. In the third line of the above equation, you put the 4 in the front of the right side of the equation (instead of at the far right which might seem more natural) for two reasons. Using the same techniques, we can easily calculate the first and last digits of the cube root of a 9 digit number (assuming, as already stated, that it is known to be the cube of a whole number). The equation to solve the problem is therefore: X 3 = 9 Then, when we solve for X, we get the answer: 2.0800838230519 the cube root of 67 is about. If I understand your question correctly, it would have been better much clearer if you had asked: Express the cube root of (the decimal number) 9 as a base 3 number. Of course, if you plug the cube root of 9 into a calculator, you get an endless stream of digits. So, for example, looking at 580093704, we compare 580 to 512 and 729, to deduce that the cube root is between 800 and 900. Srivatsan. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. The cube root of 9 can be written with a mathematical symbol as follows: ∛ 9 . Cube Roots up to 9 Digits. Source: square-root.net. We can approximate it and the cube root of 5 is about 1.70997595 Here you can find its value, what the parts of cbrt 9 are called, and what the inverse operation means.
