Write the number in standard form. 1: 8×10^−3 = 2: 5×10^2 = 3: 2.7×10^−4 = 4: 4.4×10^−5 = 5: 2.1×10^3 = 6: 1.66×10^9 = 7: 3.85×10^−8 =

Your moving the decimal point  1) since exponent is negative move three places to the left to be 0.008 2) since the exponent is positive decimal is moved 2 times to the right to be 500   I hope this helps the rest yo u do the same if negative exponent move to left the decimal amount of places Nd if positive to the right number of spaces

I know you don't need these answers anymore but for the other people:

Step-by-step explanation:

1. 0.008

2. 500

3. 0.00027

4. 0.000044

5. 2100

6. 1660000000

7. 0.0000000385

(And on big maths ideas for the other answers number 23 (9.725x10^6) = 9725000 and question 15 is 70,000,000.)

Hope you get 100% like I did :).
