4.1 x 10^4 - 1 x 10^3 = ?

### 3 Answers | Add Yours

We have to find out the value of:

(4.1 x 10^4) - (1 x 10^3)

Now 10^4 = 10000, and 10^-3 = 1000

Therefore:

(4.1 x 10^4) - (1 x 10^3) = (4.1 x 10000) - (1 x 1000)

= 41000 - 1000

= 40000

10^4=10*10*10*10=10000

10^3=10*10*10=1000

First term:

4.1*10^4=4.1*10000=41000.0 (1), shifted decimals 4 places right as we multiplied by 10000.

Second term:

1*10^3=1*1000=1000. (2)

From(1) and(2):

4.1*10^4 -1*10^3 = 41000-1000 =40000 ,

(As 41 thousand-1 thousand =40 thosand or

41 cow-1 cow =40 cow.)

4.1 x **10^4** - 1 x **10^3** = ?

Multiply 10 by itself 4 times (for 10^4) and then 3 times (for solving 10^3) to remove both powers and then further simplify it

4.1 * 10000 -1 x 1000

Applying the rules of BODMAS we need to multiply first then add or subtract

41000 -1000

**40000 Answer.**
