Options

  • m = 3, n = 3

  • m = 3, n = 2

  • m = 3, n = 5

  • m = 3, n = 1

Solution

m = 3, n = 2
 
We have,
\[ \left( y_2 \right)^5 + \frac{4 \left( y_2 \right)^3}{y_3} + y_3 = x^2 - 1\]
\[ \Rightarrow y_3 \left( y_2 \right)^5 + 4 \left( y_2 \right)^3 + \left( y_3 \right)^2 = y_3 \left( x^2 - 1 \right)\]
\[\text{ The highest order derivative is }y_3\text{ and its highest exponent in this equation is 2.}\]
Therefore, order is 3 and degree is 2. 
Hence, m = 3, n = 2
