网考网解析:
试题答案: 答案解析:When dealing with scientific notation, the power that 10 is raised to gives you the number of spaces you must move the decimal place, either to the right (for a positive value), or to the left (for a negative value). To turn 4.237 into 423,700,000, you must move the decimal place 8 spaces to the right. Therefore, 10 needs to be raised to the power of 8 (10 8 ). document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
