Answer 2

Answer:

Value of 64÷(-16) is (-4).

Step-by-step explanation:

Given,

$64 \div ( - 16)$

$\frac{64}{ (- 16)} \\ = - \frac{64}{16}$

By prime factorisation,

$64 = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \\ 16 = 2 \times 2 \times 2 \times 2$

So,

$- \frac{64}{16} = \frac{2 \times 2 \times 2 \times 2 \times 2 \times 2}{2 \times 2 \times 2 \times 2} \\ = - \frac{2 \times 2}{1} \\ = - (2 \times 2) \\ = - 4$

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)
