Express each number in standard form.
$2.9 \times 10^{- 5}$

Short Answer

Expert verified

$2.9 \times 10^{- 5}$ can be written in standard form as 0.000029.

Step by step solution

Step 1. Write steps to convert scientific notations to standard form.

1. In $x \times 10^{m}$ , check whether $m > 0$ or $m < 0$ .

2. If $m > 0$ , move the decimal point m places towards the right and if $m < 0$ , move the decimal point $- m$ places towards the left.

3. Insert zeros, decimal point and commas as required for place value.

Step 2. Apply steps to convert scientific notation to standard form.

Here, $m = - 5$ , that is, $m < 0$ .

Move the decimal point $- 5$ places towards the left.

$2.9 \times 10^{- 5} \to 0.000029$

Step 3. Write a given number in standard form.

Therefore, $2.9 \times 10^{- 5}$ can be written in standard form as 0.000029.
