Question

Find the product of 98 and 863.

Answer 1

Answer:
84574

Explanation:
Product means "multiplication"
Therefore, we will multiply 98 and 863 to get their product

98 can be expanded as follows:
98 = 90 + 8

Therefore:
863 * 98 can be rewritten as follows:
863*(90+8)

Using distributive property, we will get:
863 * 98 
= 863*(90+8)
= 863(90) + 863(8) .............> equation I

Now, we will compute each of the above terms separately:
1- Computing 863*8:
863 * 8 = 6904 ......> II

2- Computing 863*90:
863 * 90 = 863 * 9 * 10
We will compute 863 * 9 first and them multiply their product by 10:
863 * 9 = 7767
Now, we will multiply the product by 10:
863 * 90 = 863 * 9 * 10
              = 7767 * 10
              = 77670 ...........> III

Substitute with II and III in equation I to get the final product as follows:
863(90) + 863(8) 
= 77670 + 6904
= 84574 ............> This is the final result

Hope this helps :)

Answer 2

Answer:

98 × 863 = 84574.

Step-by-step explanation:

Given :  98 and 863.

To find : Product.

Solution : We have given  98 and 863.

We need to find the product

98 × 863

We can write 98 as (100 - 2)

(100 - 2) × 863

Using distributive property (a +b ) *c = a *c + b *c

100 × 863 - 2× 863.

86300 - 1726

We get 84574

Therefore, 98 × 863 = 84574.
