Answer 4

1950000

Answer 5

is 1950000 is thousand

Answer 6

To add two numbers in scientific notation, they must first have the same exponent. Let's choose \(3.2 \times 10^4\) and \(1.95 \times 10^6\).

### Step 1: Adjust the numbers to have the same exponent

We can convert \(3.2 \times 10^4\) to have the same exponent as \(1.95 \times 10^6\). Since \(10^6\) is larger than \(10^4\), we will convert \(3.2 \times 10^4\) to \(10^6\):

\[
3.2 \times 10^4 = 3.2 \times 10^4 \cdot \frac{10^2}{10^2} = 3.2 \times 100 \times 10^{-2} = 320 \times 10^{-2}
\]

So, we rewrite \(3.2 \times 10^4\) as:

\[
320 \times 10^{-2}
\]

### Step 2: Make the addition

Now we can add \(320 \times 10^{-2}\) and \(1.95 \times 10^6\) after converting \(1.95 \times 10^6\) to match the exponent:

\[
1.95 \times 10^6 = 1.95 \times 10^6 \cdot \frac{10^{-4}}{10^{-4}} = 1.95 \times 10^2 \times 10^4 = 195000 \times 10^{-4}
\]

Convert \(320 \times 10^{-2}\) into \(10^{-4}\):

\[
320 \times 10^{-2} = 320 \times 10^{2} \cdot 10^{-4} = 32000 \times 10^{-4}
\]

### Step 3: Add the two numbers

Now we can add:

\[
32000 \times 10^{-4} + 1950000 \times 10^{-4} = (32000 + 1950000) \times 10^{-4} = 1982000 \times 10^{-4}
\]

### Step 4: Convert back to scientific notation

Now we convert \(1982000 \times 10^{-4}\) back to scientific notation:

\[
1982000 = 1.982 \times 10^6
\]

So,

\[
1982000 \times 10^{-4} = 1.982 \times 10^{2}
\]

### Final Result

Thus, the sum of \(3.2 \times 10^4\) and \(1.95 \times 10^6\) is:

\[
1.982 \times 10^{2}
\]

Answer 7

Sure! Here’s a simplified version showing the work:

1. Choose numbers:
3.2 × 10^4
1.95 × 10^6

2. Adjust to the same exponent:
Convert 3.2 × 10^4 to 10^6:
3.2 × 10^4 = 0.032 × 10^6

3. Add the numbers:
0.032 × 10^6 + 1.95 × 10^6
= (0.032 + 1.95) × 10^6
= 1.982 × 10^6

4. Final answer:
1.982 × 10^6

Answer 8

Let's choose the numbers \(1.95 \times 10^6\) and \(2.56 \times 10^{-2}\) for subtraction.

1. **Write the numbers**:
\(1.95 \times 10^6\)
\(2.56 \times 10^{-2}\)

2. **Adjust to the same exponent**:
Convert \(1.95 \times 10^6\) to have an exponent of \(10^{-2}\):
\(1.95 \times 10^6 = 1.95 \times 10^6 \cdot \frac{10^{-4}}{10^{-4}} = 1.95 \times 10^2 \times 10^4 = 1,950,000 \times 10^{-4}\)
Alternatively, \(2.56 \times 10^{-2}\) can be written as
\(2.56 \times 10^{-2} = 0.0000256 \times 10^6\)

3. **Convert \(2.56 \times 10^{-2}\) to have an exponent of \(10^6\)**:
\(2.56 \times 10^{-2} = 0.0000256 \times 10^6\)

4. **Rewrite for easy subtraction**:
We can keep both numbers in terms of \(10^6\):
\(1.95 \times 10^6 = 1,950,000 \times 10^{-4}\)
\(2.56 \times 10^{-2} = 0.0000256 \times 10^6\)

5. **Perform the subtraction**:
\(1.95 \times 10^6 - 2.56 \times 10^{-2}\)
= \(1.95 \times 10^6 - 0.0000256 \times 10^6\)
= \((1.95 - 0.0000256) \times 10^6\)
= \(1.9499744 \times 10^6\)

6. **Final result**:
\(1.9499744 \times 10^6\)

Answer 9

Sure! Here's a simplified version:

1. Choose numbers:
1.95 × 10^6
2.56 × 10^-2

2. Adjust to the same exponent:
Convert 1.95 × 10^6 to 10^-2:
1.95 × 10^6 = 1950000 × 10^-2

3. Now we have:
1950000 × 10^-2
2.56 × 10^-2

4. Subtract the numbers:
1950000 × 10^-2 - 2.56 × 10^-2
= (1950000 - 2.56) × 10^-2
= 1949997.44 × 10^-2

5. Final answer:
1.94999744 × 10^6

Answer 10

I apologize for any confusion. Here is the subtraction step by step in a clear and simple format:

1. Choose numbers:
1.95 × 10^6
2.56 × 10^-2

2. Convert 1.95 × 10^6 to the same exponent as 2.56 × 10^-2:
1.95 × 10^6 = 1950000 × 10^-2

3. Now we have:
1950000 × 10^-2
2.56 × 10^-2

4. Subtract the numbers:
1950000 - 2.56 = 1949997.44

5. Write the result in scientific notation:
1949997.44 × 10^-2 = 1.94999744 × 10^6

Final answer:
1.94999744 × 10^6

Answer 11

Yes, 1,950,000 is one million nine hundred fifty thousand. If you break it down:

- It has 1 million (1,000,000)
- Followed by 9 hundred thousand (900,000)
- Followed by 5 ten thousand (50,000)
- And 0 thousand (0)
- Finally, it has 0 tens and 0 units.

So in full, it is one million nine hundred fifty thousand, which can also be referred to as one million nine hundred fifty in the context of scientific notation when considering powers of ten.
