  • 2. 

    Write 0.45 x 10 9 in scientific notations

    Explanation
    The given number, 0.45 x 10^9, can be expressed in scientific notation by moving the decimal point one place to the right and adjusting the exponent accordingly. This results in 4.5 x 10^8.

    Rate this question:

  • 3. 

    Write 652.8 x 10 6  in scientific notations

    Explanation
    The given number, 652.8 x 10^6, can be expressed in scientific notation by moving the decimal point to the left until there is only one digit to the left of the decimal point and multiplying it by a power of 10. In this case, we move the decimal point 6 places to the left, resulting in 6.528. Since we moved the decimal point 6 places, we multiply by 10^6. Therefore, the number can be written as 6.528 x 10^8.

  • 4. 

    Write .00000325 in scientific notations.

    Explanation
    The given number, 0.00000325, can be written in scientific notation as 3.25 x 10^-6. In scientific notation, the number is expressed as a decimal between 1 and 10 (in this case, 3.25) multiplied by a power of 10 (in this case, -6). The negative exponent indicates that the decimal point is moved 6 places to the left, resulting in a very small number.

    Rate this question:
