Question 1174444
<br>
(1) The expression as you show it, "1.487^3-1/1.487^3+1", means {{{1.487^3-1/1.487^3+1}}}.<br>
I doubt that is what you intended.  Use parentheses where required.<br>
(2) You don't say what you/we are supposed to do with the expression.<br>
(3) If you mean "(1.487^3-1)/(1.487^3+1)", or {{{(1.487^3-1)/(1.487^3+1)}}}, and the question is simply to evaluate the expression, then use a calculator.  You can do that as easily as we can.<br>
