Malaygoel, it's not that your wrong it's just that the answer needs to be in simplest radical form, otherwise it would've taken maybe 4 seconds to do.7.96(2.4494 - 2)
where did you get ?
You've done two things wrong in your expression. First off if you want to turn 15.92 into a radical number you need to remember this rule:√23.94 - √15.96 = √7.98/2 = 3.9
It doesn't equal this:
and you also subtracted radicals incorrectly, remember these rules:
Thanks to you both for that information. I stayed on it until about midnight last night and had had enough of that problem. I keep trying no matter if I get the problem wrong but sometimes it easier seeing someone else show where you've gone wrong. Thanks you very much!!
