Question

A number having $7$ at its ones place will have $3$ at the ones place of its cube.

• A. True
• B. False

Answer 1

The correct option is A True

The given statement is 'a number having $7$ at its ones place will have $3$ at the ones place of its cube.'

Let us take some examples to understand the given statement:

Cube of $7=7\times 7\times 7=343$

Cube of $17=17\times 17\times 17=4913$

Cube of $27=27\times 27\times 27=19683$

Thus we can say that a number having $7$ at its ones place will have $3$ at the ones place of its cube.

Therefore, the given statement is true.
