सूत्र

k × [[a, b], [c, d]] = [[ka, kb], [kc, kd]]

Multiply every element by the scalar.

det(kA) = k^n × det(A) for an n×n matrix (k² × det for 2×2)

Scalar multiplication distributes over addition: k(A + B) = kA + kB

(jk)A = j(kA)

Multiply [[1,2],[3,4]] by scalar 3.

What is scalar multiplication?

Scalar multiplication multiplies every element of a matrix by a single number (the scalar). It scales the entire matrix uniformly.

How does scalar multiplication affect the determinant?

For an n×n matrix, multiplying by scalar k multiplies the determinant by k^n. For a 2×2 matrix, the determinant is multiplied by k².

Is scalar multiplication the same as matrix multiplication?

No, scalar multiplication multiplies every element by a number. Matrix multiplication involves dot products of rows and columns of two matrices.
