Solve :

(a) Multiply the monomials and simplify the result: \((3x) \cdot (4x^2)\)

(b) Expand the product of a monomial and a binomial, and simplify: \(3x \cdot (5x + 7)\)

(c) Expand and simplify the product of two binomials: \((4x + 3)(5x + 8)\)

(d) Multiply a binomial and a trinomial. Write the expanded and simplified form: \((3x + 3)(6x^2 + 4x + 7)\)

(e) Multiply two binomials. Expand and simplify the expression: \((5x - 3)(3x + 5)\)

(f) Square the binomial and simplify: \((1x + 9)^2\)

(g) Find the product of two binomials and simplify: \((4x - 3)(1x - 8)\)

(h) Multiply a monomial and a trinomial, then simplify the result: \(4x \cdot (5x^2 - 5x + 8)\)

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

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