Step-by-step explanation:

Square of a number:-

• Any number when multiply by itself two times, the resultant number is known as the square of a number.

Recall the sign rules,

• $(+)\times(+)=(+)$
• $(+)\times (-)=(-)$
• $(-)\times (+)=(-)$
• $(-)\times (-)=(+)$

Using the sign rule, simplify as follows:

⇒ 49 × (1)

⇒ 49

Final answer: The value of the square of a number -7 is 49.
