Determine the quotient of (7.7 × 10–2) ÷ (2.2 × 10–2). Write your answer in scientific notation. A)

3.5 × 10–2

B)

3.5 × 10–4

C)

3.5

D)

3.5 × 104

C) 3.5

Step-by-step explanation:

You do 7.7 divided by 2.2 which gives you 3.5. Then just divide the exponents seperately and when dividing you subtract the exponents. Since you are subtracting you will have (-2)-(-2) and when you subtract a negative number it becomes addition because the two --  cancel out. So it is -2+2 which is equal to 0. 10 to the power of 0 (or any number to the power of 0) is always equal to 1. So 3.5 x 1 is the answer which gives you C.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

i think the answer is true
