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 \(\boxed{345.84}\).
