To express 672 in two significant figures, you focus on the first two digits: 6 and 7. Rounding 672 to the nearest ten based on the third significant figure (which is 2) gives you 670. Therefore, in two significant figures, 672 becomes 670. Remember, significant figures help convey the precision of a number, so when you're working with zeroes, only count those that are necessary to express the value accurately! Fun fact: in scientific contexts, significant figures are used to ensure that calculations reflect real-world precision.
