What is 3. 9, 27, 81, 243 can someone plz help

This is an exponent problem. 3 to the power of 4 or maybe 5

Step-by-step explanation:

Each number in this pattern is multiplied by 3

c. (3,2,6) is the answer.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
