Find the value of the determinant.
4 8 10
4 0-1
3 - 2 4

- 240

Step-by-step explanation:

We have to find the value of the following determinant  

Now, we know that the value of a general determinant is given by [a( ei - fh) + b(fg - di) + c(dh - eg)]

Therefore, the value of the given determinant is

= 4[0 × 4 - (-1)(-2)] + 8[3(-1) - 4 × 4] + 10[4(-2) - 3 × 0]

= - 8 - 152 - 80 = - 240 (Answer)
