What is the value of this expression?

[tex]\[ (-2)^5 \][/tex]


Sagot :

To determine the value of the expression [tex]\((-2)^5\)[/tex], we need to multiply [tex]\(-2\)[/tex] by itself five times. This involves repeated multiplication, as follows:

[tex]\[ (-2) \times (-2) \times (-2) \times (-2) \times (-2) \][/tex]

Let’s proceed step-by-step with the multiplications:

1. First, multiply the first two terms:
[tex]\[ (-2) \times (-2) = 4 \][/tex]
This is because the product of two negative numbers is positive.

2. Next, multiply the result by the next [tex]\(-2\)[/tex]:
[tex]\[ 4 \times (-2) = -8 \][/tex]
Multiplying a positive number by a negative number yields a negative result.

3. Continue by multiplying [tex]\(-8\)[/tex] by another [tex]\(-2\)[/tex]:
[tex]\[ -8 \times (-2) = 16 \][/tex]
Multiplying two negative numbers gives a positive result again.

4. Finally, multiply the result by the last [tex]\(-2\)[/tex]:
[tex]\[ 16 \times (-2) = -32 \][/tex]

Therefore, the value of the expression [tex]\((-2)^5\)[/tex] is:

[tex]\[ \boxed{-32} \][/tex]
