The radius of a hydrogen atom is 0.0000000529177 of a millimeter. Express this number as an approximation.

To express the number as an approximation, we can round it to the nearest whole number.

The given number is 0.0000000529177.

Rounding to the nearest whole number, we get 0 millimeters.

At the end of fiscal year 2004, the federal debt of Country C is $278,560,125,000. What is the closest estimation of this amount? Express your answer in the form of a single digit times an integer power of 10.

3x10 Exponent = 11
2x 10 Exponent = 11
2.79x 10 Exponent = 11
3x10 Exponent = -11

To express the value of the radius of a hydrogen atom as an approximation, we can round it to a more convenient decimal place. In this case, let's round it to five decimal places:

0.0000000529177 ≈ 0.00000

Therefore, the approximation for the radius of a hydrogen atom is approximately 0.00000 millimeters.

To express the given number as an approximation, we can round it to a more manageable value.

The radius of a hydrogen atom is 0.0000000529177 of a millimeter. To simplify this value, we can round it to a reasonable decimal place. Let's round it to 0.000000053 millimeters.

In scientific notation, this can be written as 5.3 x 10^(-8) millimeters. Here, the term "10^(-8)" means moving the decimal point 8 places to the left.

Therefore, the approximation of the radius of a hydrogen atom is 5.3 x 10^(-8) millimeters.
