Introduction

In this article, we will simplify the given mathematical expression: $${ (-2)^4 \times (-2) \times (-2)^2 }$$. This expression involves exponentiation, multiplication, and simplification of negative numbers. We will break down the solution into manageable steps, making it easy to understand and follow.

Understanding Exponents

Before we dive into the solution, let's quickly review the concept of exponents. An exponent is a small number that is raised to the power of a larger number. In the given expression, we have three instances of exponents: $(-2)^4$ , $(-2)^2$ , and $(-2)$ . We will simplify each of these instances separately.

Simplifying $(-2)^4$

To simplify $(-2)^4$ , we need to raise $-2$ to the power of $4$ . This means we need to multiply $-2$ by itself four times:

$(-2)^4 = (-2) \times (-2) \times (-2) \times (-2)$

Using the rule of multiplication, we can simplify this expression as follows:

$(-2)^4 = (-2) \times (-2) \times (-2) \times (-2) = 16$

So, $(-2)^4 = 16$ .

Simplifying $(-2)^2$

To simplify $(-2)^2$ , we need to raise $-2$ to the power of $2$ . This means we need to multiply $-2$ by itself twice:

$(-2)^2 = (-2) \times (-2)$

Using the rule of multiplication, we can simplify this expression as follows:

$(-2)^2 = (-2) \times (-2) = 4$

So, $(-2)^2 = 4$ .

Simplifying $(-2)$

The expression $(-2)$ is already simplified. It is equal to $-2$ .

Multiplying the Simplified Expressions

Now that we have simplified each of the expressions, we can multiply them together:

$(-2)^4 \times (-2) \times (-2)^2 = 16 \times (-2) \times 4$

Using the rule of multiplication, we can simplify this expression as follows:

$16 \times (-2) \times 4 = -128$

So, the final simplified expression is $-128$ .

Conclusion

In this article, we simplified the given mathematical expression: $${ (-2)^4 \times (-2) \times (-2)^2 }$$. We broke down the solution into manageable steps, making it easy to understand and follow. We reviewed the concept of exponents, simplified each of the expressions, and multiplied them together to get the final answer. The final simplified expression is $-128$ .
