Pls help me with these.pls its urgent. the right one will get brainliest.

 8. 1.2 × 10⁻⁶  1.2 × 10⁻³  1.2 × 10³  1.2 × 10⁵  1.2 × 10⁶

9a.  6.85 × 10⁻⁷ m   0.00000052 m   4.6 × 10⁻⁷ m

9b.  BGYR shortest to greatest

10.  6 × 10⁵   3 × 10³

11a. 10⁻⁷

11 b i.   8 × 10⁻⁷

11 b ii.  0.0000008

Step-by-step explanation: 8: the image is a bit out of focus, so it's hard to tell what all the exponents are. Just remember that for negative exponents, the larger the number, the smaller the value.

9.  Following the examples given, the exponent tells how many places to count from right to left to move the decimal from standard form to wavelength and vice-versa.  

9b. Just put the numbers from standard form in order and find the corresponding color.

10. For multiplication, multiply the numbers to the left of the × and add the exponents of the 10.   For division, Divide the numbers on the left and subtract the exponents of 10.

11a  add the powers. Just like the first part of #10

11b same procedure as #10  (The more you practice, the more likely you will remember)

The total number of decimal places in the factors will be the number of decimal places in the product. 0.002 has 3 decimal places. 0.0004 has 4 decimal places. Total of 7. SO "0" decimal . then six 0's then the multiplied number 8 in 7th place.
