What is 0.0000000405 in standard notation

8 0

0.0000000405 in scientific notation is 4.05 x 10^-8

You would move the decimal until after the 4, which will be 8 times. And since the zeros are in front so the number is really small, the exponent will be a negative.

What is (5 7/8 minus 6 3/4) minus 2 1/4 ? Please give me the correct answer and stepy by step instructions.

MaRussiya [10]

(5 7/8-6 3/4)-2 1/4
Solve the numbers in the parenthesis ( I change the denominators to a common denominator that 8 and 4 share)
(5 7/8 - 6 3/4)-2 1/4
^
-1 1/8-2 1/4
(I use KKC aka Keep Change Change where I keep -1 1/8 the same, change the minus sign to a plus sign, and change the -2 1/4 to positive) ( I change the denominators to a common denominator that 8 and 4 share)
-1 1/8 + +2 1/4 = 1 1/8
