Answer 2

Answer:

Required standard form is $( - \frac{2}{5} )$

Step-by-step explanation:

Here given,

$142 \div ( - 355)$

We want to convert it into it's standard form.

Now,

$142 \div ( - 355) \\ = \frac{142}{ - 355}$

Now by prime factorization,

$142 = 2 \times 71 \\ 355 = 5 \times 71$

so,

$\frac{142}{ - 355} \\ = \frac{2 \times 71}{ - 5 \times 71} \\ = \frac{2}{ - 5} \\ = - \frac{2}{5}$

Required standard form is $( - \frac{2}{5} )$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
