Question

The cube root of 0.000729 is........?

• A. 0.9
• B. 0.09
• C. 0.009
• D. 0.0009

Answer 1

The Correct Option is B

For finding the cube root of \(0.000729\), we can write it in a simpler form:

\(0.000729 = \frac{729}{1000000} = \frac{729}{(100)^3}\)

We know that the cube root of \(729\) is \(9\) because \(9^3 = 729\)

Thus, the cube root of \(0.000729\) is:

\(\sqrt[3]{0.000729} = \frac{9}{100} = 0.09\)

Therefore, the cube root of \(0.000729\) is \(0.09\).

So, The correct option is (B).
