However this gives an incorrect answer, and the correct one is obtained only when the #1/2# is first factorised. Why is this the case? Calculus

How do supernovae work? Why does the H-R diagram look different for star clusters of different ages? What is the cross product of # [4,-3,2]# and # [3,1,-5] #? How do you solve #log (x + 8) = 1 + log (x - …
