It’s the sams equation, just negative cause it’s reflected on the x-axis
Answer:
errr polynomials ahaha
so basically we can multiply the power outside of the parantheses with the exponents on the inside:
so

this will give us:
-3x^8y^4
we also unfortunately, have to use the power on the coefficient -3 as well and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)
so:
-3*-3*-3*-3=81
final expression

Answer:
cos -60° =
,
cos 660° = 
Step-by-step explanation:
hope it helps
Domain is all the x values represented
domain here is infinitely because it can go on forever to the left and to the right
