Recall the unreal number i²=-1
so -36 can be written into 36i², which is (6i)²
so 3√-36 + 2√-64= 3(6i)+2(8i)=18i + 16i=34i

Answer:
15 students
Step-by-step explanation:
No. of boys students = No. of all students - No. of girls
no. of boys =50-15 = 35 boys
the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys
and the girls that will play the match are 5 girls
so, no of students chosen to play = 5+10=15 students
The answer I believe would be -6
