Fill in the blanks with correct number beginvmatrix 3 & 2 \\ 4 & 5 endvmatrix = 3× square - square × 4 = square - 8 = square

Answer: 3 × 5 − 2 × 4 = 15 − 8 = 7 For beginvmatrix a & b \\ c & d endvmatrix = ad - bc . Here a = 3, b = 2, c = 4, d = 5 . = 3× 5 - 2× 4 = 15 - 8 = 7 So the boxes are 5, 2, 15 and 7.

Fill in the blanks with correct number: |3 2; 4 5| = 3 × [ ] − [ ] × 4 = [ ] − 8 = [ ]

Fill in the blanks with correct number\[\begin{vmatrix} 3 & 2 \\ 4 & 5 \end{vmatrix} = 3\times \square - \square \times 4 = \square - 8 = \square\]

Answer: 3 × 5 − 2 × 4 = 15 − 8 = 7

For \(\begin{vmatrix} a & b \\ c & d \end{vmatrix} = ad - bc\). Here \(a = 3, b = 2, c = 4, d = 5\).

\[= 3\times 5 - 2\times 4 = 15 - 8 = 7\]

So the boxes are 5, 2, 15 and 7.
