the answer is 67
Step-by-step explanation:
Answer:
B) -7
Step-by-step explanation:
since since since there is more of the negative number then the positive number, the positive number gets canceled out.
Positive exponent? An index would imply that the base, x, had a fractional exponent.
My Dear Aunt Sally used to say, "If there's a negative exponent in your face, then flip your base!"
In other words, if the exponent is negative, take the reciprocal of the base, x →

and change the exponent to positive.
Therefore:

I have cross the fraction bar line change the exponent sign.
Answer:
see below
Step-by-step explanation:
<em><u>sin(a+b) = sin(a)cos(b) + cos(a)sin(b)</u></em>
sin(π+q) = sin(π)cos(q) + cos(π)sin(q)
sin(π) = 0
cos(π) = -1
therefore
sin(π+q) = 0*cos(q) -sin(q) = -sin(q)
