Question

which expression is equivalent to 83,120 in expanded form using powers of 10

Answer 1

8*10000+3*1000+1*00+2*10+2

Answer 2

The expression is equivalent to 83,120 in expanded form using powers of 10 is $8\times 10^4+3\times 10^3+10^2+2\times10^1.$

Step-by-step explanation:

We have,

83,120

To find, the expanded form using powers of 10 = ?

83,120 = 8,0000 + 3,000 + 100 + 20 + 0

= 8 × 10000 + 3 × 1000 + 100 + 2 × 10 + 0

$=8\times 10^4+3\times 10^3+10^2+2\times10^1$

$=8\times 10^4+3\times 10^3+10^2+2\times10^1$

∴ The expanded form using powers of 10

$=8\times 10^4+3\times 10^3+10^2+2\times10^1$

Hence, the expression is equivalent to 83,120 in expanded form using powers of 10 is $8\times 10^4+3\times 10^3+10^2+2\times10^1.$
