I wrote my question wrong. It should be write 25000000 in expanded notation using the power of 10
2.5×10^7
Your number is 25,000,000. In scientific notation, you never show more than the ones place in your answer and every number has a decimal point - even if you don't see one. If you don't see one, it is on the right-hand side. Therefore, your number is actually 25,000,000. with a decimal at the end. Now count the numbers to the right until you have one number left - the 2. You moved seven places. Place the decimal there to get 2.5. Next, to get to the original number again, you would have to multiply 2.5 by 10,000,000, or 10^7 power (the number of spaces you counted). Therefore, your answer is 2.5 x 10^7

25000000
No problem! To write 25,000,000 in expanded notation using the power of 10, we need to express it as a product of a number between 1 and 10 and a power of 10.
Here's how we can do it:
Step 1: Count the number of zeros in 25,000,000. In this case, there are seven zeros.
Step 2: Move the decimal point to the left of the last digit to get a number between 1 and 10. In this case, we get 2.5.
Step 3: Express the power of 10 by raising it to the number of zeros counted in step 1. Since there were seven zeros, the power of 10 is 10^7.
Putting it all together, we can write 25,000,000 in expanded notation using the power of 10 as:
2.5 × 10^7
So, 25,000,000 can be expressed as 2.5 multiplied by 10 raised to the power of 7.
