Matrices by following steps:
- step0: Evaluate the determinant:
  $$\left[\begin{array}{ll}{1}&{-4}\{5}&{-5}\end{array}ight]$$
- step1: Use the appropriate notation:
  $$\left|\begin{array}{cc}{1}&{-4}\{5}&{-5}\end{array}ight|$$
- step2: Evaluate the determinant:
  $$1	imes \left(-5ight)-\left(-4	imes 5ight)$$
- step3: Calculate:
  $$-5-\left(-4	imes 5ight)$$
- step4: Calculate the product:
  $$-5-\left(-20ight)$$
- step5: Remove the parentheses:
  $$-5+20$$
- step6: Add the numbers:
  $$15$$
Vamos a calcular el determinante de la matriz $$ \left|\begin{array}{cc}1 & -4 \ 5 & -5\end{array}ight| $$.
El determinante de la matriz es $$ 15 $$.
El determinante de la matriz es $$ 15 $$.
