Answer:
1726 to the nearest 100 = 1700
I assume it is the last one, 3n^2, because the degree is the exponent, which is two and the three is the coefficient, which is next to the variable, plus it is a monomial, so there is only one term, eliminating the first two, the third one is just reversed. Therefore, the answer should be the last one. Hope this helps. :)
0.000000109 in scientific notation will look as it follows:
1.09 * 10^-7
or
<span>
1.09 E-7
It's the same as 1.09 * (-10000000)
I hope it'll give you some clue of scientific notation with decimals.</span>
