the half - life of uranium is 2.5 x 10^5 years. what is this in standard form?
Answer
Explanation:
Step1: Recall the rule of scientific - to - standard conversion
When we have a number in scientific notation (a\times10^{n}), if (n> 0), we move the decimal point (n) places to the right.
Step2: Move the decimal point
For (2.5\times10^{5}), since (n = 5), we move the decimal point in (2.5) five places to the right. So (2.5\times10^{5}=250000).
Answer:
250000
