Question

X3+7x-10 при х = -3​

Answer 1

Ответ:

${x}^{3} + 7x - 10 = {( - 3)}^{3} + 7 \times ( - 3) - 10 = - 27 - 21 - 10 = - 58$

$x3 + 7x - 10 = - 3 \times 3 + 7 \times ( - 3) - 10 = - 9 - 21 - 10 = - 40$

я не поняла примера поэтому я решила два варианта, первый есть степень и второй без степень

Answer 2

To find the value of the expression x^3 + 7x - 10 when x = -3, we substitute -3 into the expression and calculate the result.

Replacing x with -3, we have:

(-3)^3 + 7(-3) - 10

Simplifying this expression:

-27 + (-21) - 10

Combining the terms:

-27 - 21 - 10

Performing the subtraction:

-48 - 10

Giving us the final result:

-58

Therefore, when x = -3, the value of the expression x^3 + 7x - 10 is -58.
