Question

-9 x^3 = -9 × 1/27 выполните значение выражения

Answer 1

Решение:
$-9*x^3 = -9 * \frac{1}{27}$
Разделим обе части уравнения на - 9, получим
$x^3 = \frac{1}{27}$
$x^3 = (\frac{1}{3} ) ^{3}$
$x = \frac{1}{3}$
Ответ:  $\frac{1}{3}$

Answer 2

To evaluate the expression, simply replace the variable 'x' with the given value (-1/27) and perform the arithmetic calculation:

-9 x^3 = -9 × (1/27)

Now, substitute 'x' with (-1/27):

-9 × (-1/27)^3

To raise a fraction to a power, you raise both the numerator and the denominator to that power:

-9 × (-1)^3 / 27^3

Since (-1)^3 equals -1, and 27^3 equals 19683, the expression becomes:

-9 × (-1) / 19683

Now, perform the remaining arithmetic:

-9 / 19683

This fraction cannot be simplified further, so the final value of the expression is:

-9 / 19683 ≈ -0.0004574
