One type of insect is 0.0052 meter long. what is the length in scientific notation.
sp2606 [1]

Here, we need to write the length of the insect in scientific notation.

The given length of the insect is 0.0052 meter

Now, to write 0.0052 meter in scientific notation we need to follow this:

Scientific notation always start with non-zero digit followed by a decimal point.

Since in our number the decimal is needed to be moved three places to the right to get the first non-zero digit.

The exponent of the 10 is -3.

10^{-3}=\frac{1}{1000} =0.001

Therefore, our number 0.0052 can be written as:

5.2 \times 10^{-3}

Hence, the require scientific notation is 5.2 \times 10^{-3}.
