Sorry I don’t know that one but I recommend using the app photomath it really helps
The 5 is in the hundredths place, so you would look at the number before it, which is 9. Since 9 is greater than 4, you will round the 5 up to 6
So it would be 1.86

The larger value is 9 x 10^9
The smaller value is 3 x 10^(-4)
Divide the larger over the smaller
Doing so will have you divide the coefficients 9 and 3 (numbers in front of the "times ten to the..." portions) to get 9/3 = 3.
Then you'll also subtract the exponents: 9 minus (-4) = 9 - (-4) = 9 + 4 = 13
In summary so far, we got a coefficient of 3 and an exponent of 13
So the final answer is 3 x 10^13 (assuming you want scientific notation)
If you want to convert to standard notation, instead of scientific notation, move the decimal point in 3.0 thirteen spots to the right to get
30,000,000,000,000
there are 13 zeros (four groups of 3 plus one just after the 3) in that value above. This is the number 30 trillion

Pull out 3 (common factor):
3(y-6)
A) 3(y-6) is the correct answer
