Answer 2

Answer:

2198 is the odd one as this is not a perfect cubic number.

Step-by-step explanation:

Provided numbers: 1331, 1728, 2198, 2744

In this provided set of numbers;

Three numbers are perfect cubic numbers.

• For the first one 1331 we can see that;

$\sqrt[3]{1331} = 11$Hence 11 is the cubic root of 1331.

• For the second number 1728 we can see that;

$\sqrt[3]{1728} = 12$

Hence 12 is the cubic root of 1728.

• For the third number 2198 we can see that;

$\sqrt[3]{2198} = 13.00197209$So 2198 is not a perfect cubic number. Insted 13 is the cubic root of 2197 actually.

• For the fourth number 2744 we can see that;

$\sqrt[3]{2744} = 14$

So 14 is the cubic root of 2744.
