Solve :

(a) Multiply the monomials and simplify the result: \((4x) \cdot (6x^2)\)

(b) Expand the product of a monomial and a binomial, and simplify: \(3x \cdot (5x + 8)\)

(c) Expand and simplify the product of two binomials: \((2x + 4)(5x + 9)\)

(d) Multiply a binomial and a trinomial. Write the expanded and simplified form: \((6x + 3)(7x^2 + 2x + 5)\)

(e) Multiply two binomials. Expand and simplify the expression: \((5x - 6)(4x + 6)\)

(f) Square the binomial and simplify: \((2x + 8)^2\)

(g) Find the product of two binomials and simplify: \((2x - 4)(2x - 8)\)

(h) Multiply a monomial and a trinomial, then simplify the result: \(6x \cdot (7x^2 - 4x + 7)\)

(i) Expand and simplify the product of two binomials: \((6x + 3)(5x - 4)\)

(j) Multiply a trinomial and a binomial. Write the simplified expression: \((4x^2 + 3x + 5)(4x + 6)\)
