What is the cardinal number of the set a
The only issue is that you did not continue the solution to its completion…. There are six roots in all, not just the two given. This stems from the fact that x^3 =1 has three roots (1, -.5 + i*(√3)\2, and -.5 - i*(√3)\2 ) …. and similarly, x^3=-8 has three roots (-2, 1+i*√3, and 1-i*√3 ). As this is a 6th order polynomial, it has six roots.
AN ANGEL ON EARTH!!!!
THANK YOU SO MUCH <3 !!
Thank you v.much
Thank you my sister

What is the difference between a Menu 6,6,3 and Menu 6,7,3. one is confidence interval, and the other is a Stat test, but I dont know what that means.
Awesome
if only our teacher explained it like this, thank you! i finally understand
