1) 6*10=60, 6*7=42/2=21, 21+60=81
2) 12*12=144, 12*12=144*3.14=452.16/2=226.08, 144+226.08=370.08
3) 14*5=70, 5*10=50, 70+50=120 (maybe)
4) 6*5=30/2=15, 4*3=12/2=6,15+6=21
5) 6*6=36*3.14=113.04/2=56.52, 5*5=25*3.14=78.5/2=39.25, 56.52+39.25=95.77

Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2
Hence,
After 6 days, 3 bottles will be left.
The value of x = ㏑120 = 4.78749 . . .
Since eˣ = 120, taking the natural logarithm of both sides, we have
㏑eˣ = ㏑120
x㏑e = ㏑120
Dividing though by ㏑e, we have
So, x = ㏑120/㏑e
x = ㏑120/1 (since ㏑e = 1)
x = ㏑120
x = 4.78749
So, the value of x = ㏑120 = 4.78749 . . .
