Find the second moment of area, the location of the neutral axis, and the distances from the neutral axis to the top and bottom surfaces. consider that the section is transmitting a positive bending moment about the z axis, mz, where mz = 10 kip·in if the dimensions of the section are given in ips units, or mz = 1.13 kn·m if the dimensions are in si units. determine the resultant stresses at the top and bottom surfaces and at every abrupt change in the cross section.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
