Is there a general rule for finding ?

this expression is true only because the exponent is 1

if it were another power you could not do this

other wise the rule is power to power

as to ussually if you break it into mutliple expressions using the rule - November 6th 2009, 01:06 PMViral
This should help you :) .

the exponent rules ussually just use as default

can mean

as you mention probably doesn't relate to much here

but in certain other expressions it would

what you are doing is correct...

it can just get very busy....

on the TI89 use the expand((a+b)^4) and its done

calculus has some better ways to deal with this.

aloha and have nice weekend
