Question

Quizplus · Accepted Answer

Standard form of a number requires writing it using digits only, without any written words or symbols. Therefore, the number in standard form would be 638,997. Choice A is missing the last three digits, choice B adds three extra zeros at the end, and choice D switches the last two digits. The number can be written as 638,997 in standard form, as it is already in thousands, hundreds, tens, and ones place. Option A is not correct as it only represents the thousands, leaving out the hundreds and ones. Option B is incorrect as it adds extra zeros without representing the correct place values. Option D is incorrect as it switches the position of the last two digits.
