The attendance of the Strawberry Festival over two weeks was 645,300. Write the number in expanded form using exponents.

6*10^5 + 4*10^4 + 5*10^3 + 3*10^2

Step-by-step explanation:

Let's break it down.

6*10^5 is 6 times 10 to the 5th power. That means 6*100,000. = 600,000.

4*10^4 is 4 times 10 to the 4th power. That means 4*10,000. = 40,000.

5*10^3 is 5 times 10 to the 3rd power. That means 5*1,000. = 5,000.

Finally, 3*10^2 is 3 times 10 to the 2nd power. That means 3*100. = 300.

Add it all up and you get 645,300.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
