Dan wrote (2x10^6)+(3x10^4)+(5x10^3)+4 for the expanded form of two millions , three hundred fifty thousand, four. what error did he make in the expanded form? what is the standard form of the number?

Part 1) Dan wrote in expanded form two millions thirty five thousand, four instead of  two millions , three hundred fifty thousand, four

Part 2) The standard for of the number is

Step-by-step explanation:

we have

The number two millions , three hundred fifty thousand, four

we know that

Dan Wrote

The number that Dan wrote is two millions thirty five thousand, four

The correct number in expanded form is

The standard for of the number is

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
