Solve :

(a) Multiply the monomials and simplify the result: \((7x) \cdot (5x^2)\)

(b) Expand the product of a monomial and a binomial, and simplify: \(2x \cdot (6x + 5)\)

(c) Expand and simplify the product of two binomials: \((1x + 6)(4x + 8)\)

(d) Multiply a binomial and a trinomial. Write the expanded and simplified form: \((4x + 2)(7x^2 + 5x + 7)\)

(e) Multiply two binomials. Expand and simplify the expression: \((5x - 5)(3x + 7)\)

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

(g) Find the product of two binomials and simplify: \((4x - 7)(2x - 8)\)

(h) Multiply a monomial and a trinomial, then simplify the result: \(7x \cdot (7x^2 - 3x + 7)\)

(i) Expand and simplify the product of two binomials: \((6x + 2)(2x - 3)\)

(j) Multiply a trinomial and a binomial. Write the simplified expression: \((3x^2 + 4x + 3)(6x + 8)\)
