== Q4 ==<br />
<br />
i have a question on Q4. for the part a^-1=a^2, if it's true, then a*a^2=1, which makes a=1....but a can't be 1 right?<br />
<br />
I don't see why <math>a*a^2=1</math> implies <math>a=1</math>. --[[User:Drorbn|Drorbn]] 06:16, 22 September 2006 (EDT)<br />
<br />
because <math>b=a^{-1}=a^2</math>, if ab=1, why shouldn't <math>a*a^2=1</math>?</div>142.150.49.62https://drorbn.net/index.php?title=Talk:06-240/Homework_Assignment_1&diff=2007Talk:06-240/Homework Assignment 12006-09-22T19:58:45Z<p>142.150.49.62: </p>
