Step-by-step explanation:

To simplify : $(-5 )4 \times (-5)$

Solution:

• Multiplication is a process of repetitive addition of integers.
• Multiplication rules for integers :

1. If two negative integers are multiplied then the product obtained is positive integer. i.e. $(-) \times(-)=+$
2. If one negative and one positive integers are multiplied then the product obtained is negative integer. i.e.$(-) \times(+)=-$
3. If both positive integers are multiplied then the product obtained is positive integer. i.e. $(+) \times(+)=+$

• Therefore according to above rule we solve .

        $(-5 )4 \times (-5) \\\\= (-20)\times (-5 ) \\\\= 100$
