Chapter 5: Problem 85

Write each number in decimal notation without the use of exponents. $$7.9 \times 10^{-1}$$

Short Answer

Expert verified
The decimal notation for \(7.9 \times 10^{-1}\) is 0.79.

Step by step solution

01

Identify the decimal number and the exponent

Given number in scientific notation is \(7.9 \times 10^{-1}\). Here, 7.9 is the decimal number and -1 is the exponent of 10.
02

Handle Negative Exponent

Negative exponents indicate division by that power of 10. In other words, the decimal point should move to the left by the value indicated by the exponent.
03

Moving the Decimal Point

So, in this part, the decimal point in 7.9 should be moved 1 place to the left as indicated by exponent -1. That gives us the number 0.79
