Answer:
what is the figure
Step-by-step explanation:
Your question has been heard loud and clear.
First one (x+2i)(x-2i) = x^2+4
Second one (x-2+2i)(x-2-2i) = x^2-4x+8
Third one (x+1+i)(x+1-i) = x^2+2x+2
Thank you
Edit: Sorry for taking 15 minutes I was calculating lol
Answer:
option (b)
Step-by-step explanation:
Concentration of [H+} = 5.4 x 10^-14
According to the formula
pH = - log [H+]
![pH = - log[5.4\times 10^{-14}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%5B5.4%5Ctimes%2010%5E%7B-14%7D%5D)
![pH = - log[5.4] -log [10^{-14}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%5B5.4%5D%20-log%20%5B10%5E%7B-14%7D%5D)
pH = 14 - log 5.4
pH = 14 - 0.732
pH = 13.3
Thus, the pH is 13.3
