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
