In Exercises 1–14, write each number in decimal notation without the use of exponents. 1.4X10⁰

Key Concepts

Decimal Notation

Decimal notation is a way of expressing numbers using a base of ten, where each digit represents a power of ten. For example, the number 1.4 in decimal notation means 1.4 times ten to the power of zero, which is simply 1.4. Understanding how to convert numbers from scientific notation to decimal notation is essential for accurately interpreting and using numerical data.

Scientific Notation

Scientific notation is a method of expressing very large or very small numbers in a compact form, typically as a product of a number between 1 and 10 and a power of ten. In the example given, 1.4 x 10⁰ indicates that the number is 1.4 multiplied by 1 (since 10⁰ equals 1). Recognizing how to manipulate and convert scientific notation is crucial for solving problems in algebra.

Powers of Ten

Powers of ten are expressions that represent ten multiplied by itself a certain number of times, denoted as 10^n, where n is an integer. For instance, 10⁰ equals 1, 10¹ equals 10, and 10² equals 100. Understanding powers of ten is fundamental in both scientific notation and decimal notation, as it helps in determining the scale and value of numbers.
