you just need to know the exponential rules

x^0=0

$x^{-a}=\frac{1}{x^a}$

x^1=x

I'll just do some since you should get practice yourself and they're pretty similar

reember pemdas/order of operations, exponents before multiply

I like to factor them first so I don't get the order mixed up

$2m^0n^{-4}=$

$(2)(m^0)(n^{-4})=$

$(2)(1)(\frac{1}{n^4}=$

$\frac{2}{n^4}$

$-x^2y^{-2}=$

$(-1)(x^2)(y^{-2})=$

$(-1)(x^2)(\frac{1}{y^2})=$

$\frac{-x^2}{y^2}$

12)

$-3k^{-1}=$

$(-3)(k^{-1})=$

$(-3)(\frac{1}{k^1}=$

$\frac{-3}{k}$
