Question

Add 3.2 x 10^4 + 1.95 x 10^6

Answer 1

1 982 000 (or 1.982 x 10^6 in standard form)

Explanation:

We have to take into account BIDMAS when answering this question.

First we do indicies:

10^6 = 1 000 000

10^4 = 10 000

Then Multiplication

1.95 x 1 000 000 = 1 950 000

3.2 x 10 000 = 32 000

And finally addition:

1 950 000 + 32 000 = 1 982 000

Answer 2

To add 3.2 x 10^4 and 1.95 x 10^6, we need to make the exponents of the numbers the same.

1. Rewrite the numbers in scientific notation:

3.2 x 10^4 + 1.95 x 10^6

2. To make the exponents the same, we can rewrite 3.2 x 10^4 as 0.32 x 10^5:

0.32 x 10^5 + 1.95 x 10^6

3. Now that the exponents are the same (both 5), we can add the numbers:

0.32 x 10^5 + 1.95 x 10^6 = 0.32 x 10^5 + 19.5 x 10^5

4. Add the numbers:

0.32 x 10^5 + 19.5 x 10^5 = (0.32 + 19.5) x 10^5

5. Simplify the sum:

(0.32 + 19.5) x 10^5 = 19.82 x 10^5

6. Finally, rewrite the result in scientific notation:

19.82 x 10^5 = 1.982 x 10^6

Therefore, 3.2 x 10^4 + 1.95 x 10^6 = 1.982 x 10^6.

the silly!!!
