Question

4+5
`4+5(x)/(y) 3x^(2) - 3x^(2)`

Answer 1

`58 + \frac{ {15x}^(3) }{y} - {3x}^(2)`

Explanation:

1) Use this rule: a/b × c/d = ac/bd.

`4 + 54 + \frac{5x * {3x}^(2) }{y} - {3x}^(2)`

2) Take out the constants.

`4+54 + \frac{(5 * 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 + (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.
