The diameter of a human hair is 9 \cdot 10^{-5}9⋅10 −5 9, dot, 10, start superscript, minus, 5, end superscript meters. the diameter of a spider's silk is 3 \cdot 10^{-6}3⋅10 −6 3, dot, 10, start superscript, minus, 6, end superscript meters. how much greater is the diameter of a human hair than the diameter of a spider's silk?

Given that the diameter of a human hair

Given that the diameter of a spider's silk

Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk.

To find that we just need to subtract the given numbers.

Since powers are not same so let's make them equal

now we can easily subtract the coefficients that is 3 from 9

Hence final answer is .

The above answer is correct I showed u the steps down below! I hope this helps! This is from khan academy, by the way.
