How do you write #0.00000124# in scientific notation?

1 Answer

# 1.24 xx 10^-6 #


In scientific notation the value of the number is expressed as a decimal with one digit in the ones place and the other significant digits written to the right of the decimal. Then this decimal is multiplied by a power of 10

In the problem above the decimal point needs to be moved six places to the right. This is the same as dividing by 1,000,000 or
#10^6 #

# 1/(1,000,000) = 10^-6# a negative exponent is an expression of dividing.
