Cannot use calculator then use the below indices law with
fractional indices loh.
ya × yb = ya+b
(ya)b = ya×b
A fractional power means that you have to take a root of the
number. For example, 4½ means take the square root of 4
= 2. Similarly, x1/3 means take the cube root of x.
We can use the rule (ya)b =
ya×b to simplify complicated index expressions.
(1/8)-1/3; = [(1/8)-1]1/3 =
[8]1/3 = 2
Amazing shit right this google?
