# Write the eccentricity of the hyperbola 9x^{2} – 16y^{2} = 144.

Answer :

**Given:** 9x^{2} – 16y^{2} = 144

**To find:** eccentricity(e)

9x^{2} – 16y^{2} = 144

**Formula used:**

For hyperbola

Eccentricity(e) is given by,

Here, a = 4 and b = 3

⇒ c = 5

Therefore,

**Hence, eccentricity is**
