Answer 2

Answer:

(-1)×(-1)×(-1)×(-1)×(-1) is equal to (-1).

Step-by-step explanation:

Given,$(-1)×(-1)×(-1)×(-1)×(-1)$

This is a problem of Algebra's simplification.

For solving this problem first we should know all operations of sign of Algebra.

I.e$1.( + ) \times ( + ) = ( + )$

$2.( + ) \times ( - ) = ( - )$

$3.( - ) \times ( + ) = ( - )$

$4. ( - ) \times ( - ) = ( + )$

Now,

$( - 1) \times ( - 1) \times ( - 1) \times ( - 1) \times ( - 1) =( + 1 )\times ( - 1) \times ( - 1) \times ( - 1) = ( - 1) \times ( - 1) \times ( - 1) = ( + 1) \times ( - 1) = ( - 1) = - 1$

After simplication value of the given term is (-1).

Some extra important formulas of Algebra,

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)
