Hey dear❤

Answer....

Determinant of an upper (lower) triangular or diagonal matrix equals the product of its diagonal entries. ... detA =detAT,

so we can apply either row or column operations to get the determinant. 2. If two rows or two columns of A are identical or if A has a row or a column of zeroes, then detA = 0.
