Answer: 2, and 33
Step-by-step explanation:
The simplified value of the expression given as 3^2018 + 3^2015 / 3^2017 + 3^2016 is 7/3
<h3>How to evaluate the expression?</h3>
The expression is given as:
3^2018 + 3^2015 / 3^2017 + 3^2016
Factor out 3^2015 in the expression
So, we have
3^2015(3^3 + 1)/3^2015(3^2 + 3)
Cancel out the common factor
(3^3 + 1)/(3^2 + 3)
Evaluate the exponents
(27 + 1)/(9 + 3)
This gives
28/12
Simplify
7/3
Hence, the simplified value of the expression given as 3^2018 + 3^2015 / 3^2017 + 3^2016 is 7/3

Answer:
C) – 1
Step-by-step explanation:
E = cos20º + cos40º + cos60º +cos80° + cos 100°+cos120° +cos140° +cos160º + cos180º
E= 0.9 + 0.76 + 0.5+0.17+(-0.17)+(-0.5)+(-0.76) + ( – 0.9 ) + (– 1 )
E= 0.9 + 0.76 + 0.5 +0.17 - 0.17 - 0.5 -0.76 – 0.9 – 1
E= – 1
So ; equal – 1
