|x| or abs(x) depending on what you are asking about.
First, simplify the equation: absolute (3x-1) = absolute (x+5) absolute (2x) = absolute (6) absolute (x) = absolute (3) which really means plus or minus 3, or, (+/-3) Now you have x = +/- 3, so test out x = 3 and x = -3. Test out x = 3: absolute (3*3-1) = absolute (3+5) absolute (9-1) = absolute (8) ---> absolute 8 = absolute 8 --> 8=8 which is correct! Now test x = -3 absolute (3*(-3)-1) = absolute (-3+5) ---> absolute (-9-1) = absolute (2) absolute (-10) = absolute 2 ---> 10 = 2 Since 10 does not equal 2, this is not a correct answer. Therefore x = 3.
The standard notation for 3.5 x 10-3 is 0.0035
0.002 in Scientific Notation = 2 x 10-3
3 x 107 is already in scientific notation (: 30,000,000 is the standard notation (if that's what you meant to ask)
2 x 2 x 2 x 3 x 3 = 72 In exponential notation, that's 2^3 x 3^2
4.8 x 10-3 in standard notation = 0.0048
8.58 x 10^-3
7540 in scientific notation is 7.54 x 10^3.
The scientific notation for 0.005702 is 5.702 x 10^-3.
2.5e-3 or 2.5 x 10-3
0.003 in scientific notation is 3 x 10^-3
