Question

Use scientific notation to simplify the expression. Give the answer in standard notation.

5.8 × 10^2
----------
2.9 × 10^−2

Answer 1

Divide 5.8 and 2.9, then since it is scientific notation with division, you would take the exponents and SUBTRACT. So since it is negative 2, it would be 2+2, and the answer would be 2*10^4

Answer 2

5.8 / 2.9 = 2
10^2 / 10^-2 = 10^4
ergo: it all equals 2 x 10^4

Answer 3

If it was multiplication, you would add the exponents. So if it was 5.8*10^2 TIMES 2.9*10^-2, you would add them, thus making the answer 16.82*10 Since 2+-2 is 0.
