Question

PLLLEEEAASSEE HELP ME explain how you got the answer

Answer 1

For # 1, the answer will be 1 because of the exponential rule $a^{0} = 1$.

#2, the answer is going to be $x^{4}$ because of the exponential rule $a^{-b} = \frac{1}{a ^{b} }$.

#3. I'm not sure that this could be simplified any further.

#4  To get the answer to this question, we must apply the distributive property, along with the exponential rule $a ^{m} × a ^{n} = a ^{m+n}$. When we apply these properties, we'll get $- \frac{3}{x^4}$

For the other questions, they all apply the Laws of Exponents.
