which answer shows 8.45×10⁴ written in standard form?\n0.000845\n8,450\n84,500\n8,450,000
Answer
Explanation:
Step1: Recall scientific - notation rule
When we have a number in scientific notation (a\times10^{n}) ((1\leqslant a<10)), if (n> 0), we move the decimal point (n) places to the right.
Step2: Move the decimal point
For (8.45\times10^{4}), since (n = 4), we move the decimal point 4 places to the right. Starting with 8.45, we get 84500.
Answer:
84,500
