Answer 1

Let's evaluate each statement one by one.

1. 3×10×10×10=3×10^3

   • The left side simplifies to \(3 \times 10^3\), which is equal to the right side.
   • Answer: Yes

2. 400,000=4×10^6

   • The left side, 400,000, can be expressed as \(4 \times 10^5\) (not \(4 \times 10^6\)).
   • Answer: No

3. 7×10^5=7×100,000

   • The left side is \(7 \times 10^5\) and \(10^5\) is equal to 100,000. Thus, both sides are equal.
   • Answer: Yes

4. 5 × 1,000=5,000

   • The left side simplifies to \(5 \times 1000\), which is equal to 5,000.
   • Answer: Yes

So the final answers are:

1. Yes
2. No
3. Yes
4. Yes
