### 0.00001 =

• A.

10⁵

• B.

10

• C.

10⁻⁵

C. 10⁻⁵
Explanation
The given expression 0.00001 can be rewritten as 10⁻⁵. This is because 0.00001 is equivalent to dividing 1 by 100,000, which can be expressed as 1/10⁵. In scientific notation, 10⁻⁵ represents a number that is 10 raised to the power of -5, which is the same as dividing 1 by 10⁵. Therefore, the correct answer is 10⁻⁵.

### 10 ⁻¹ =

• A.

0.1

• B.

101

• C.

10

A. 0.1
Explanation
The given expression is 10⁻¹. This means that we have a base of 10 raised to the power of -1. When a number is raised to a negative power, it means that we need to take the reciprocal of that number. Therefore, 10⁻¹ is equal to 1/10, which is equivalent to 0.1.

### 475 x 1000 =

475000
475, 000
475,000
Explanation
The correct answer is 475,000. The multiplication of 475 by 1000 results in shifting the decimal point three places to the right, which gives us 475,000.

### 0.00574 x 100 =

0.574
Explanation
To find the product of 0.00574 and 100, we multiply 0.00574 by 100. Multiplying 0.00574 by 100 gives us 0.574.

Rate this question:

• 7.

### 59801 ÷ 100 =

598.01
Explanation
The given question involves dividing 59801 by 100. When we divide a number by 100, we move the decimal point two places to the left. Therefore, the decimal point in 59801 will move two places to the left, resulting in 598.01. Thus, the answer is 598.01.

Rate this question:

• 8.

### 0.47 ÷ 10 =

0.047
Explanation
When dividing a number by 10, the decimal point is moved one place to the left. In this case, 0.47 divided by 10 results in 0.047.

Rate this question:

• 9.

### 54 x 10⁶ =

54000000
54 000 000
54,000,000
Explanation
The correct answer is 54,000,000. This is because when multiplying 54 by 10⁶, we move the decimal point six places to the right, resulting in a number that has six zeros after the 54.

Rate this question:

• 10.

### 0.0038 x 10⁴ =

38
Explanation
The given equation is a multiplication problem where 0.0038 is multiplied by 10⁴. When we multiply 0.0038 by 10⁴, we move the decimal point four places to the right, resulting in 38. Therefore, the answer to the equation is 38.

Rate this question:

• 11.

### 8599.3 ÷ 10³ =

8.5993
Explanation
