Hey there, Lets solve your question together
Question - <span>What is 400 in Expanded form ?
</span>
We know that expanded form is a spread out way to write a number by showing the value of each individual digit that contributes<span> to make the full number.
</span>
Lets use an example to show expanded form
Number - 4,265
= 4 x 1,000 + 2 x 100 + 6 x 10 + 5 x 1
Now lets solve for the number 400 in expanded form.
The number "4" is in the hundreds place
The number "0" is in the tenths<span> place
</span>
<span>The number "0" is in the One's place
</span>Therefore 400 in expanded form is 400+00+0.
<span> Hope this helps </span>
<span>You run 0.5 miles every 3 minutes => 1 mile every 6 minutes. Your friend runs 2 miles every 14 minutes => 1 mile every 7 minutes. You run a whole number of miles every number of minutes that is a multiple of 6. Your freind runs a whole number of miles every number of minutes that is a multiple of 7 Then the least possible number of miles that you both run to end at the same time is the least common factor of 7 and 6 minutes. This is 7 * 6 = 42 minutes. You will have run 42 min / (6 miles/min) = 7 miles, and your friend will have run 42 min / (7 miles/min) = 6 miles</span>
The top part equals 1 because anything to the power of zero equals one. then for the second one bring every variable with a negative exponent to the top and leave the 2 at the bottom
