Question

By using cube root table, estimate the cube roots of the following numbers, correct to two places of decimal: 732​

Answer 1

Answer:

732 is 5.20 decimal in 7.32

Answer 2

Answer:-

9.01

Step by step explaination:-

$732 = 61 \times 12 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.936 \times 2.289 \\ \: \: \: \: \: \: \: \: \: \: \: \: = 9.009504 \\ \: = 9.01$

Steps:-

1. First,we have to broke it into two numbers in form of multiply that are 61 and 12.
2. Then,we have to find cube root of them from cube root table that is of 61 is 3.936 and of 12 is 2.289.
3. Now, multiply them and answer of multiplication is 9.009504.
4. We have to find it correct to two decimal places.So,there comes 9 after two decimal places which is greater than 5.So,we have to round off of it.
5. So,the answer is 9.01.
