Answer:
3rd choice
Step-by-step explanation:
In division for variables with same base, you do subtract top exponent minus bottom exponent. She did that correctly since -3-(-1)=-3+1=-2 and -2-1=-3.
The problem said m=-2 and n=4 and she replace m with (-2) and n with (4). She did this correctly.
You can multiply base numbers unless the exponents are the same 4 doesn't have the exponent -2 on it so you can't do (4(-2))^(-2)
The error is the 3rd option.

Answer:
tangent: y- 
= -4(x - 
)
Step-by-step explanation:
differentiating
isolating y' to one side and simplifying
when x = 
,
y' = 
y' = 
tangent: y- = -4(x - )
Step-by-step explanation:
3/4 + 1/2= 3+2/4= 5/4
