The smallest marine fish known is the dwarf goby. The average length of this fish is just 3.39 x 10^-1 inches. What is this number in standard form?

A.339
B.33.9
C.0.339
D.0.0339
C

Thanks that's what I got.

To convert a number from scientific notation to standard form, we move the decimal point to the right if the exponent is positive or to the left if the exponent is negative. In this case, the exponent is negative, so we move the decimal point to the left.

The number in scientific notation is 3.39 x 10^-1.

Moving the decimal point once to the left gives us 0.339.

Therefore, the number in standard form is 0.339, which corresponds to option C.

3.39 * 10^-1 = 3.39*0.1 = 0.339
