10 × 10 × 10 = 1000 combinations
Answer: 1000
Arctan(3.4) ≈ 73.6°. You can view the 3.4 as the slope of a line. Then it is clear the the 52.9 and 99.8 can't be right. If you have to do this without a calculator, it can be quite tricky...
Answer:

Step-by-step explanation:
From the question we are told that
The non separable differential equation 
Generally the chi form of a give equation is mathematically represented as







for c=0

Therefore


Yo got to the calculator click scientific then click 9 the go to the left side where all the x's are then click the one that looks like the y is on the top right next to the x and then click 6 and then click enter and then you get 531441
