He said the square root of 89 is ...Mr. H's answer:<br /><br />He said the square root of 89 is <br />9 8/19.<br /><br />What Mr. H did correct:<br /><br />His denominator of 19 was correct. <br />He probably did the shortcut that was told in class today.<br /><br />Shortcut:<br /> You subtract the first perfect square from the next perfect square.<br /><br />In this case the perfect square before 89 is 81 and the perfect square after 89 is 100. <br />So 100-81 = 19<br /><br />What else did Mr. H did correct:<br /><br />His whole number was 9 which is correct.<br /><br />I found a shortcut to find the whole number.<br /><br />Shortcut:<br /> Find the factor of the perfect square before the number you are trying to solve.<br /><br />In this case the perfect square before 89 is 81. So when you look at your chart the factor of 81 is 9x9 so 9 is your whole number. <br /><br />What Mr. H did wrong:<br /><br />When he was counting the numbers when he was trying to find the numerator he included the first perfect square.<br /><br />This is what he did:<br /><br />(81 82 83 84 85 86 87 88 89) 90 91 92 93 94 95 96 97 98 99 100<br /><br />To help you avoid that mistake I'll tell you another shortcut that will make things faster and easier.<br /><br />Shortcut:<br /> You subtract the perfect square before the number you are trying to solve from the number you are trying to solve.<br /><br />In this case the perfect square before 89 is 81. So 89-81 = 8 so that is your numerator. <br /><br />* Those shortcut will help you avoid common mistakes other people make. I hope you understand my explanation.tears_77https://www.blogger.com/profile/15212609612353788333noreply@blogger.comtag:blogger.com,1999:blog-1019297942530526331.post-48561699366096117922006-11-08T20:21:00.000-06:002006-11-08T20:21:00.000-06:00you got the question wrong mr h because u counted ...you got the question wrong mr h because u counted the perfect square.<br />The corect answer is 9 8/19. To do this question first i found out wat times wat equals 81 that how i found the whole number. Then to find the numerator i counted how much numbers <br />are between 81 an 89 and theres 8 numbers. so the numerator is 8 now to find the numerator you count how mant numbers are between 81 to 100 and there nineteen numbersand u don't count from 81 u start from 82. That how u get the answer which is 9 8/19 that my explaination.Grand Master Flash_abdulhttps://www.blogger.com/profile/02187962737449862110noreply@blogger.comtag:blogger.com,1999:blog-1019297942530526331.post-37413108608652852312006-11-08T18:22:00.000-06:002006-11-08T18:22:00.000-06:00You got it wrong because you counted the perfect s...You got it wrong because you counted the perfect square and you were not suppose to. the corredct answe is 9 and 8 over 19. You do this question by [81] 82 83 84 85 86 87 88 [89] 90 91 92 93 94 95 96 97 98 99 [100] there are now 19 numbers the factor of 81 is 9 so the mixed number is 9 and becouse it is a perfect square it has to be a whole number so the number is 1 over 81 # 82 will be 1 over 19 becouse there are 19 numbers and 82 is the first number that you count # 83 will be 2 over 19 and so on that is my explnation on how you answer that question.<br /> By: Lisa Medeiros <br /> 8-41LisaMhttps://www.blogger.com/profile/01969866803973669805noreply@blogger.com
