Three to the fourth means multiply 3 together 4 times, so expanded form is 3 x 3 x 3 x 3.

You are correct

Step-by-step explanation:

Another way to do it is 4 x 4 x 4 and that would equal 12.

Hope this helps :)

This is correct :)

Step-by-step explanation:

3^4= (3)(3)(3)(3)

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
