Question

What is 820.681 in expanded form, using powers of 10?

Answer 1

Answer:

$820.681=8\times 10^2+2\times 10^1+0\times 10^0+6\times 10^{-1}+8\times 10^{-2}+1\times 10^{-2}$

Step-by-step explanation:

Given : Number 820.681.

To find : What is number in expanded form, using powers of 10?

Solution :

Number in expanded form, using powers of 10 using number system,

Hundred  Tens   Ones    Tenths    Hundredths    Thousandths

     8             2         0           6                8                       1

$820.681=8\times 10^2+2\times 10^1+0\times 10^0+6\times 10^{-1}+8\times 10^{-2}+1\times 10^{-2}$

$820.681=8\times 100+2\times 10+0\times 1+6\times \frac{1}{10}+8\times \frac{1}{100}+1\times \frac{1}{1000}$

$820.681=800+20+0+6\times 0.1+8\times 0.01+1\times 0.001$

$820.681=800+20+0.6+0.08+0.001$

Answer 2

8.00000×10^2+2.0000×10^1+ .600×10^-1+.080×10^-2+.001×10^-3=820.681 in expanded form using powers of 10
