Question

What is this number in standard form 4x100 8x10 9x1 8 x 1/100 5x1/1000

Answer 1

The number in standard notation is 489.085, found by adding each component represented by its place value: 400 (4×100), 80 (8×10), 9 (9×1), 0.08 (8×1/100), and 0.005 (5×1/1000).

Step-by-step explanation:

The number in standard form is written by combining the individual values represented by each place value and decimal place value. In the given number, we have 4×100 (four hundreds), 8×10 (eight tens), 9×1 (nine ones), 8×1/100 (eight hundredths), and 5×1/1000 (five thousandths). To write this number in standard notation, we simply add together all of these parts.

So, the number in standard form is:

• 400 (from 4×100)
• + 80 (from 8×10)
• + 9 (from 9×1)
• + 0.08 (from 8×1/100)
• + 0.005 (from 5×1/1000)

Adding these together, we get:

400 + 80 + 9 + 0.08 + 0.005 = 489.085

Standard notation is the usual way of writing numbers without exponents, and it provides a clear and concise representation of the number without the use of scientific notation or place value multipliers.

Answer 2

The number in standard form is 489.085, which combines values from hundreds to thousandths place. Scientific notation is another way to express large or small numbers by finding a decimal between 1 and 10 and pairing it with a power of 10.

Step-by-step explanation:

The number in standard form that you're asking about is made up of different place values combined: 4x100 (hundreds), 8x10 (tens), 9x1 (ones), 8 x 1/100 (hundredths), and 5x1/1000 (thousandths). To write this number in standard form, we add up these values:

4x100 = 400

8x10 = 80

9x1 = 9

8 x 1/100 = 0.08

5x1/1000 = 0.005

Adding these together gives us: 400 + 80 + 9 + 0.08 + 0.005 = 489.085.

Scientific notation is another way to express numbers, particularly very large or very small ones. For instance, 56900 can be written as 5.69 times 10 to the fourth power, and 0.000028 can be written as 2.8 times 10 to the negative fifth power. Converting a number into scientific notation typically involves finding a decimal between 1 and 10 and an appropriate power of 10.
