    Write 0.000456 in scientific notation.Example:  = 5.6x10^4       No spaces necessary.

    Explanation
    The given number, 0.000456, can be written in scientific notation as 4.56x10^-4. In scientific notation, a number is expressed as a product of a decimal number between 1 and 10, and a power of 10. In this case, the decimal number is 4.56, and the power of 10 is -4. The negative exponent indicates that the number is less than 1.

    Write 4500000 in scientific notation.Example:  = 5.6x10^4       No spaces necessary.

    Explanation
    The given number 4500000 can be written in scientific notation as 4.5x10^6. In scientific notation, a number is expressed as a product of a decimal number between 1 and 10 (in this case, 4.5) and a power of 10 (in this case, 10^6). This notation is commonly used to represent very large or very small numbers in a concise and standardized format.

    Write 0.00715 in scientific notation.Example:  = 5.6x10^4       No spaces necessary.

    Explanation
    The given number, 0.00715, can be written in scientific notation as 7.15x10^-3. In scientific notation, a number is expressed as a product of a decimal number between 1 and 10, and a power of 10. In this case, the decimal number is 7.15, and the power of 10 is -3, indicating that the decimal point should be moved three places to the left to obtain the original number.

    Write 4500000 in scientific notation.Example:  = 5.6x10^4       No spaces necessary.

    Explanation
    The given number, 4500000, can be expressed in scientific notation as 4.5x10^6. In scientific notation, the first part of the number should be between 1 and 10, so we divide 4500000 by 10^6 to get 4.5. The exponent, 6, indicates that we need to move the decimal point 6 places to the right to get the original number. Therefore, the number 4500000 can be written as 4.5x10^6 in scientific notation.
