please explain
To express the given number, 0.0000000529177, as an approximation, we look at the given decimal places and determine the significant figures.
In this case, there are eight decimal places after the leading zero: 0.0000000529177.
Since we want to express this number as an approximation, we need to round it to the appropriate number of significant figures.
Looking at the digit after the eighth decimal place (which is a 7), we can round the number. Since 7 is greater than or equal to 5, we round up the final significant figure.
Thus, the final approximation is 0.00000005.
please explain shorter
To express the given number, 0.0000000529177, as an approximation, round it to the seventh decimal place. Since the digit after the seventh decimal place is 7 (which is greater than 5), round up the seventh decimal place. Therefore, the approximation is 0.00000005.

To determine how many times 4 × 10^4 is larger than 2 × 10^2, we can divide the first number by the second number.
(4 × 10^4) / (2 × 10^2) = 2 × 10^2
Simplifying further, we have:
2 × 10^2 = 200
Therefore, 4 × 10^4 is 200 times larger than 2 × 10^2.
