Solve :

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

(b) Expand the product of a monomial and a binomial, and simplify: \(2x \cdot (4x + 8)\)

(c) Expand and simplify the product of two binomials: \((3x + 5)(4x + 9)\)

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

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

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

(g) Find the product of two binomials and simplify: \((4x - 7)(3x - 7)\)

(h) Multiply a monomial and a trinomial, then simplify the result: \(3x \cdot (8x^2 - 4x + 10)\)

(i) Expand and simplify the product of two binomials: \((5x + 2)(4x - 1)\)

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