Chapter 1 - Section 1.7 - Scientific Notation - Exercise Set - Page 91: 75



Work Step by Step

Recall that a number written in scientific notation is expressed in the form: $$a \times 10^{n}$$ If $n$ is positive, move the decimal point in a to the right $n$ places. If $n$ is negative, move the decimal point in $a$ to the left $|n|$ places. For example: Convert $2.26\times10^-4$ to decimal notation. Since $n=-4$ is negative. The decimal point in $2.26$ will move $4$ places to the left. The resulting value will then be $0.000226$.
