**Convert between standard and scientific notation worksheet :**

Here we are going to see some practice questions based on the concept convert between standard and scientific notation.

**Question 1 :**

Write the following numbers in scientific notation.

205852

**Solution :**

Since the given number is integer, we have to consider that the decimal point is in the last place.

Here n = 5 because the decimal point is shifted five places to the left .

**Question 2 :**

Write the following numbers in scientific notation.

3449098.96

**Solution :**

Now we are going to move the decimal point so that there is only one non-zero digit to its left.

**Here n = 6 because the decimal point is shifted five places to the left .**

**Question 3 :**

Write the following numbers in scientific notation.

0.00008035

**Solution :**

Now we are going to move the decimal point to the right so that there is only one non-zero digit to its left.

Since we are moving the decimal point to the right side, we have to put negative sign in the power.

**Question 4 :**

Write the following numbers in decimal form.

5.236 x 10⁵

**Solution :**

Since we have positive number as power, we have to move the decimal point to the right side.

**Question 5 :**

Write the following numbers in decimal form.

6.415 x 10⁻⁶

**Solution :**

Since we have negative number as power, we have to move the decimal point to the left side.

We move 6 digits to the left side, we have to write zero for the remaining digits.

**Question 6 :**

Write the following numbers in decimal form.

1.72 x 10⁹

**Solution :**

We have positive number as power, we have to move the decimal point to the right side.

1.72 x 10⁹ = 1720000000

Since we have to move 9 digits to the right, we have to put zero for the remaining digits.

**Question 7 :**

How do you write 119,000 in scientific notation?

**Solution :**

Since the given number is integer, we have to consider that the decimal point is in the last place.

Now we are going to move the decimal point to the left side, so we have to put positive sign in the power.

**119000 = 1.19 x 10**⁵

**Question 8 :**

How do you write 7.2 × 10² in standard form?

**Solution :**

Since we have positive number in the power, we have to move the decimal point to the right side.

7.2 × 10² = 720

**Question 9 :**

How do you write 2,300 in scientific notation?

**Solution :**

Since the given number is integer, we have to consider that the decimal point is in the last place.

Now we are going to move the decimal point to the left side, so we have to put positive sign in the power.

**2300 = 2.3 x 10**³

**Question 10 :**

How do you write 38,000 in scientific notation?

**Solution :**

Since the given number is integer, we have to consider that the decimal point is in the last place.

Now we are going to move the decimal point to the left side, so we have to put positive sign in the power.

**38000 = 3.8 x 10**⁴
