Scientists found that the body of a male consists of 3.58×10^-4 lbs of zinc. What is the number written in standard notation?
notka56 [123]

Answer:

The number is 0.000358 lbs.

Step-by-step explanation:

Scientists found that the body of a male consists of 3.58 \times 10^{-4} lbs of zinc.

This is a scientific way of writing a number.

For, example 0.0023, a number in normal or standard notation can be scientifically written as 2.3 \times  10^{- 3}.

So, in our case, the number is 3.58 \times 10^{-4} lbs and we have to write this number in standard notation.

Then the number is 0.000358 lbs. (Answer)
