Question

Write the short form of:
a. 1 x 10^6 + 4 x 10^4+ 3 x 10^3 + 2 x 10^1+ 9 x 10^0​

Answer 1

1 x 10^6 = 1000000

4 x 10^4 = 40000

3 x 10^3 = 3000

2 x 10^1 = 20

9 x 10^0 = 9

now,

you can replace this equation 1 x 10^6 + 4 x 10^4+ 3 x 10^3 + 2 x 10^1+ 9 x 10^0​

with 1000000+40000+3000+20+9.

and now you can simply add above equation.

and your final ans is 1043029.
