Transcript text: Write the following number in standard form. \[ \begin{array}{l} (3 \times 100)+(4 \times 10)+5 \times 1)+(8 \times 0.1) \\ +(4 \times 0.01)= \end{array} \]

Solution

Solution Steps

Step 1: Expand the Expression

The given expression is:

$(3 \times 100) + (4 \times 10) + (5 \times 1) + (8 \times 0.1) + (4 \times 0.01)$

Step 2: Calculate Each Term

Calculate each term separately:

$3 \times 100 = 300$
$4 \times 10 = 40$
$5 \times 1 = 5$
$8 \times 0.1 = 0.8$
$4 \times 0.01 = 0.04$

Step 3: Sum the Terms

Add all the calculated terms together:

$300 + 40 + 5 + 0.8 + 0.04 = 345.84$

Final Answer

The number in standard form is $\boxed{345.84}$ .
