expand sqrt((x^2-4)(y^2-9))

expand

(x^{2} - 4) (y^{2} - 9)

x^{2} - 4 y^{2} - 9

Solution steps

(x^{2} - 4) (y^{2} - 9)

Apply radical rule:

ab = a b

(x^{2} - 4) (y^{2} - 9) = x^{2} - 4 y^{2} - 9

= x^{2} - 4 y^{2} - 9

7^{8} 0. 7^{- 3}

(2 y^{2} + 8) (2 y^{2} + 8)

4 e^{- 3 x}

\frac{2}{5} e^{- 0.0001216 t}
