Write each number in decimal notation without the use of exponents. $$7 \times 10^{-5}$$

Short Answer

Expert verified
The expression \(7 \times 10^{-5}\) in decimal notation without the use of exponents is 0.00007.

Step by step solution

01

Understand Negative Exponent Rule

A negative exponent such as \(-5\) in \(10^{-5}\) represents a reciprocal. Therefore, \(10^{-5}\) is equivalent to \(1 / 10^{5}\).
02

Convert to Decimal Notation

Given the rule from Step 1, \(1 / 10^{5}\) equals to \(0.00001\).
03

Apply the Multiplication

Multiply \(0.00001\) (which is the decimal equivalent of \(10^{-5}\)) by 7 to obtain the result in decimal notation.
