# Obtain the product of (i) xy, yz, zx (ii ) a, -a^{2},a^{3}

(iii) 2, 4y, 8y^{2}, 16y^{3 }(iv) a, 2b, 3c, 6abc (v) m, - mn, mnp

**Solution:**

Multiplication of two algebraic expressions or variable expressions involves multiplying two expressions that are combined with arithmetic operations such as addition, subtraction, multiplication, division, and contain constants, variables, terms, and coefficients.

(i) xy × yz × zx = x^{2} y^{2}z^{2}

(ii) a × (- a^{2} ) × a^{3 }= - a^{6}

(iii) 2 × 4y × 8y^{2 }× 16 y^{3} = 2 × 4 × 8 × 16 × y × y^{2} × y^{3 }= 1024 y^{6}

(iv) a × 2b × 3c × 6abc = 2 × 3 × 6 × a × b × c × abc = 36a^{2}b^{2}c^{2}

(v) m × (- mn) × mnp = - m^{3}n^{2} p
