Answer:
10
Step-by-step explanation:
5 choose 2 is 5x4/2, which is 20/2, which is 10.
Mili means 1000 so 1000ml=1 L (ml=milileter, L=liter)
conversion factor
1L/1000ml=1 and
1000ml/1L=1
convert 2 and 1/4 L to ml
2 and 1/4L
try to convert with second conversion thing (1000ml/1L=1)
2 and 1/4L times 1000ml/1L=2000 and 1000/4 ml=2000 and 250 ml=2250 ml
10⁶= 1 million= 1,000,000
10⁷=10 million= 10,000,000
Can you explane it a little more.
Try this option.
1 is for scalar (result is number), 2 is for vector (result is vector).
