    E. 3.56 X 10 ^2
    G. 5.67 X 10 ^ -5
    Explanation
    The correct answer choices are all written in scientific notation, which is a way to express very large or very small numbers using powers of 10. In scientific notation, a number is written as a coefficient multiplied by 10 raised to a power. For example, 5.36 x 10^5 means 5.36 multiplied by 10 raised to the power of 5. The other answer choices that are also in scientific notation follow the same pattern, with a coefficient and a power of 10.

Standard form is a way of writing numbers that includes a decimal point and digits after it, or a number multiplied by a power of 10. In this case, options 2.450, 2,450, 345.345, and 792,098 are written in standard form as they all have a decimal point and digits after it. The option 3.45 X 10^2 is also in standard form as it is a number multiplied by a power of 10. Therefore, the correct answer includes all the options that are written in standard form.
