Answer 1

Answer:

$58 + \frac{ {15x}^{3} }{y} - {3x}^{2}$

Step-by-step explanation:

1) Use this rule: a/b × c/d = ac/bd.

$4 + 54 + \frac{5x \times {3x}^{2} }{y} - {3x}^{2}$

2) Take out the constants.

$4+54 + \frac{(5 \times 3) {xx}^{2} }{y} - {3x}^{2}$

3) Simplify 5 × 3 to 15.

$4 + 54 + \frac{ {15xx}^{2} }{y} - {3x}^{2}$

4) Use the product rule: x^a x^b = x^a + b.

$4 + 54 + \frac{15xx^{2} }{y} - 3x^{2}$

5) Simplify 1 + 2 to 3.

$4 + 54 + \frac{15 {x}^{3} }{y} - {3x}^{2}$

6) Collect like terms.

$(4 + 54) + \frac{15 {x}^{3} }{y} - {3x}^{2}$

7) Simplify.

$58 + \frac{ {15x}^{3} }{y} - {3x}^{2}$

Therefor, the answer is 58 + 15x³ / y - 3x².
