QuestionConvert the number $8.5 \times 10^{-1}$ to decimal form. What is it?

Studdy Solution

STEP 1

Assumptions1. The number is given in scientific notation as $8.5 \times10^{-1}$ . . We need to convert this number into decimal notation.

STEP 2

In scientific notation, the number $a \times10^{b}$ represents the number $a$ moved $b$ places to the right (if $b$ is positive) or to the left (if $b$ is negative) on the number line.

STEP 3

In our case, the number is $8.5 \times10^{-1}$ . Here, $a =8.5$ and $b = -1$ . Since $b$ is negative, we move the decimal point in $a$ one place to the left.

STEP 4

Moving the decimal point one place to the left in $8.$ gives us $0.85$ .
So, $8. \times10^{-1}$ in decimal notation is $0.85$ .
