Answer

"6.7 x 10^2"

Explanation

## Step 1:In this problem, we are tasked with expressing the number 672 in a format that includes two significant figures. Significant figures are digits that create meaning, offering a measure of the precision of a computation or measurement. ## Step 2:In the numeral 672, all digits are significant. However, we are looking to represent this numeral using only TWO significant figures while maintaining its value.## Step 3:To fulfil this requirement, we can convert the numeral into scientific notation. In scientific notation, the number gets written as the product of its significant figure and a power of ten. In this case, the number 672 will be encoded as "6.7 x 10^2".## Step 4:The number "6.7 x 10^2" maintains the size of 672; however, it has merely two significant figures: the '6' and the '7'.
