If we have the same base, we can do this:
(1/3)^4*(1/3)*7 = (1/3)^(4+7) = (1/3)^11
3^7/3^15 = (3^7)*(3*(-15)) = 3^(7 + (-15)) = 3^(-8) = 1/(3^8)
4^5*4^2 = 4^(5+2) = 4^7
The coefficients are the numbers next to a variable (which is X in this case). Therefore, the coefficients here are 4 and 8
It could be square, rectangle, parallelogram, rhombus/diamond but, trapezoid could not be.
I believe it would be all of the above let me know if it is right
