To write 0.00145 in scientific notation, we first move the decimal so only one figure appears to the left of the decimal. Here's that shift: 0.00145 => 1.45 But we need to account for the movement with a power of ten. Moving the decimal to the right, which we just did, will mean a negative power of ten. And the power of ten will be an integer that is equal to the number of places we moved the decimal. In this case, we moved it 3 places. That means our exponent on the 10 will be a -3. Here it is: 1.45 x 10-3 And we're done.
That the last number is 5 means you round the second to last one up. This gives you .0943. However, 3 is the last number now, and that doesn't let one round up. So you are at .094. Four is the last number, and it does not allow you to round up.
So you are left with the last two digits of .09, which are the two significant figures.
