-2 to the Power of 4
Introduction
In mathematics, exponents are used to express repeated multiplication of a number by itself. The base number is multiplied by itself a certain number of times, determined by the exponent. In this article, we will explore the concept of raising -2 to the power of 4. This means multiplying -2 by itself four times. Let’s delve into the fascinating world of exponents and discover the value of -2 to the power of 4.
Understanding Exponents
Before we dive into -2 to the power of 4, let’s ensure we have a firm grasp of exponents.
What are Exponents?
Exponents, also known as powers or indices, are mathematical tools used to represent repeated multiplication. They are written as superscripts above the base number. For example, in the expression 2^3, 2 is the base number, and 3 is the exponent. It indicates that the base number, 2, should be multiplied by itself three times.
Exponents and Negative Numbers
When it comes to exponents, negative numbers introduce some interesting concepts. Raising negative numbers to even exponents results in positive numbers, while odd exponents yield negative numbers. In the case of -2 to the power of 4, we have an even exponent, so the result will be positive.
Calculating -2 to the Power of 4
Now, let’s calculate -2 to the power of 4 step by step and find out the result.
Step 1: Understanding Negative Bases
When we have a negative base, as in -2, we need to keep a few things in mind. For even exponents, the result will be positive, and for odd exponents, the result will be negative. Since our exponent, 4, is even, we can expect a positive outcome.
Step 2: Calculate -2 to the Power of 2
To find -2 to the power of 2, we multiply -2 by itself. (-2) * (-2) equals 4. Therefore, -2 to the power of 2 is 4.
Step 3: Calculate 4 to the Power of 2
Now, we need to find 4 to the power of 2. To do this, we multiply 4 by itself. 4 * 4 equals 16. Hence, 4 to the power of 2 is 16.
Step 4: Final Calculation
Finally, we calculate -2 to the power of 4 by using the result from the previous step. We multiply 16 by itself. 16 * 16 equals 256. Therefore, -2 to the power of 4 is 256.
