...thereisashortcut to simplfyingthe
expression.The disabled-expression(x2

saystake x2
multiplyfourof them.Sowhatyoureallyhave
is(x2
*x2
*x2
* x2
).Thiscan be expandedtowrittenas (x * x * x * x * x * x * x * x).Whenyou
use an exponenttogatherthe bases,youhave x8
.Or youcouldhave just mutlipliedthe powersandsaid
(2 * 4) :)
Here are some more examples:
1. (x2
)3
=x6
2. (t-2
)2
=t-4
3. (m4
)1
=m4
