Question

3854×784×5+769×216×25

Please explain The Solution

Answer 1

We can do this by Splitting some Numbers inorder to do this as Simple As Possible

3854×784×5+769×216×25

To do this simple/to make calculations simple. lets ch
​​​​change some terms

=(3800+54)×(800-16)×5+(800-31)×(220-4)×25

As per distributive Law
= (3800+54)×(800×5-16×5)+(800-31)×(220×25-4×25)

=> 800×5 Is 4000
=>16×5= 80
=>220×25 = 5500
=>4×25=100

Put these values

(3800+54)×(4000-80)+(800-31)×(5500-100)

we know 4000-80 = 3920
and 5500-100 = 5400

=(3800+54)×(3920)+(800-31)×(5400)

we have to calculate

=>3800×3920 = 14,896,000

=> 3920×54 = 211,680

=>800×5400=4,320,000

=>31×5400 = 167,400
​​​

put these


(3800×3920+54×3920)+(800×5400-31×5400)

=14,896,000+211,680+4,320,000+167,400

=19,595,080
