The coefficient is written ranging from 1.01.0 to 9.999.99.
Look at 0.0000005910.000000591. The space after the first non-zero number counting from left to right is where your decimal point will go. To make the coefficient between 1.01.0 and 9.999.99, move the decimal place 77 times to the right:
0.0000005910.000000591 rArr⇒ 5.915.91
All the zeros before the 55 in 5.915.91 do not have to be written since 00 has no value.
Finally, after moving the decimal point 77 times to the right, indicate the change you have made to 0.0000005920.000000592 by adding "x 10^-710−7" after 5.915.91.
:., 0.000000591 written in scientific notation is 5.91 x 10^-7.
