There are several different ways to write expanded form. One of them just separates the digits:

2.07 = 2 + .07

Another way to write expanded form shows the place value of each digit:

2.07 = 2*1 + 0*0.1 + 7*0.01

Yet another way to write expanded form makes use of exponents to show the place value of each digit.

2.07 = 2*10

2.07 = 2 + .07

Another way to write expanded form shows the place value of each digit:

2.07 = 2*1 + 0*0.1 + 7*0.01

Yet another way to write expanded form makes use of exponents to show the place value of each digit.

2.07 = 2*10

^{0}+ 0*10^{-1}+ 7*10^{-2}2.07 in word form is*two and seven hundredths*.
