### What is the scientific notation of 123,330? note- the exponent is represented by __^4. Here the exponent is four.

• A.

1.233 x 10^5

• B.

1233 x 10^5

• C.

1.233 x 10^8

• D.

1.233 x 10^6

A. 1.233 x 10^5
Explanation
The scientific notation of a number is a way to express it as a product of a number between 1 and 10 and a power of 10. In this case, the number 123,330 can be expressed as 1.233 x 10^5. The number 1.233 is between 1 and 10, and the exponent 5 indicates that we need to multiply it by 10 five times. Therefore, the correct answer is 1.233 x 10^5.

### What is the answer to 5 x 10^5? note- the exponent is represented by __^5. Here the exponent is 5

• A.

600,000

• B.

500,000

• C.

5 x 10^5

• D.

50,000

B. 500,000
Explanation
The answer to 5 x 10^5 is 500,000. This is because when you multiply 5 by 10^5, you are essentially multiplying 5 by 10 raised to the power of 5. This means you are multiplying 5 by 10, five times. Each time you multiply by 10, you move the decimal point one place to the right. So, multiplying 5 by 10 five times gives you 500,000.

### What's the scientific notation of 10^2 x 1.2? note- the exponent is represented by __^2. Here the exponent is 2

• A.

12.0

• B.

120

• C.

1.2

• D.

1200

B. 120
Explanation
The scientific notation of a number is a way to express it as a product of a decimal number between 1 and 10 and a power of 10. In this case, 10^2 x 1.2 can be written as 1.2 x 10^2, which is equal to 120.

### What's the answer to 8.765 x 10^11? note- the exponent is represented by __^11. Here the exponent is 11

• A.

8765000000000

• B.

87650

• C.

8.765

• D.

8765000000000000

A. 8765000000000
Explanation
The answer to 8.765 x 10^11 is 8765000000000. This is because when you multiply 8.765 by 10 raised to the power of 11, you move the decimal point 11 places to the right, resulting in a large number.
