Question

does anyone know a good website with the rules for working with brackets that are powered to fractions?
i need those special rules that tell you when to do what and when to not

Answer 1

Do you have a problem as an example?

Answer 2

yes, i have 2 functions
\[2L + K=C\]
and
\[\sqrt{L}+\sqrt{K}=y\]
i have to determine the cost function

the answer in the book is
\[y= 3^{1/2} \]
but i get
\[y=3L ^{1/4}\] from \[L ^{0.5} +(2L)^{0.5}\]

and i still dont understand why sometimes the constant is multiplied by the power and sometimes not even if the constant is inside a bracket

Answer 3

the answer in the book is \[y=3L ^{1/2},\] my bad!
