STEP 1

Assumptions1. We are given expressions that represent decimal numbers in expanded form.
. Each term in the expression represents a digit in a specific place value of the decimal number.
3. We need to convert each expression into a standard decimal form.

STEP 2

Let's start with the first expression$$( \times10)+(5 \times1)+\left(2 \times \frac{1}{10}\right)+\left(7 \times \frac{1}{100}\right)+\left(6 \times \frac{1}{1000}\right)$$

STEP 3

Calculate each term in the expression.
$$=30+5+0.2+0.07+0.006$$

STEP 4

Add up all the terms to get the decimal number.
$$=30++0.2+0.07+0.006 =35.276$$

STEP 5

Now, let's move on to the second expression$$(9 \times100)+(2 \times10)+(3 \times0.1)+(7 \times0.001)$$

STEP 6

Calculate each term in the expression.
$$=900+20+0.3+0.007$$

STEP 7

Add up all the terms to get the decimal number.
$$=900+20+0.3+0.007 =920.307$$

STEP 8

Finally, let's solve the third expression$$(5 \times1,000)+(4 \times100)+(8 \times1)+\left(6 \times \frac{1}{100}\right)+\left(5 \times \frac{1}{1000}\right)$$

STEP 9

Calculate each term in the expression.
$$=500+400+8+.06+.005$$

Add up all the terms to get the decimal number.
$$=5000+400+8+0.06+0.005 =5408.065$$So, the decimal forms of the given expressions area.35.276b.920.307c.5408.065
