Here, we want to find the value of ln (-7)
ln is same as Log to base e and mathematically , we have it for positive numbers only
For that of negative numbers, we get undefined results
However, by the use of special mathematical
methods, we have the answer for ln (-7) as;
1.94591015 + 3.14159265 i

Answer:
22
Step-by-step explanation:
The number of male friends : 200 ÷100 × 45 = 90
