Answer:
7\times (-3) \times (-2)^2=-21\times 4=-84
Step-by-step explanation:
Multiplication :
Multiplication means to add equal groups or we can say multiplication is repeated addition . We use symbol × to denote multiplication .
Consider a bag containing 5 balls then 7 bags will contain [tex]5+5+5+5+5+5+5=7+7+7+7+7=35[/tex] balls or we can directy say that 5 bags will contain 5×7 = 35 balls .
If we are saying 6 times 8, it means 8+8+8+8+8+8 = 6+6+6+6+6+6+6+6 .
i.e 8 is added 6 times or 6 is added 8 times .
In problem 7×9 = 63 , 7 and 9 are factors and 63 is the product .
To find : [tex]7\times (-3) \times (-2)^2[/tex]
Solving [tex]7\times (-3) :[/tex]
[tex]7\times (-3)=(-3) +(-3)+(-3)+(-3)+(-3)+(-3)+(-3)=-21[/tex]
Solving [tex](-2)^2 :[/tex]
[tex](-2)^2=(-2)\times (-2)=4[/tex]
Therefore ,
[tex]7\times (-3) \times (-2)^2=-21\times 4=-84[/tex]
