Standard Form/Notation, Scientific Notation and Exponential Notation are used in different countries but all have the same meaning. It is a way of expressing a number as a value between 1 and 10 multiplied by a power of 10. 106 = 1.06 x 102
If you mean 2.65 x 103 this is called standard form or, alternatively, scientific notation or exponential notation,
39
It means in powers as for example 5*5*5 in exponential notation is 5^3 which means 5 to the power of 3
It is 1.818x10 raised to the power of 3.

Standard Form, Scientific Notation and Exponential Notation are different expressions for the same thing. When a number is expressed as a value between 1 and 10 multiplied by a power of 10 it is said to be in Standard Form (or Scientific Notation or Exponential Notation). 3.4 x 10^14 : 8.9 x 10^-4 : 1.2 x 10² are all written in standard form. 15.28 x 10³ is NOT in standard form as 15.28 is not a number between 1 and 10. When converted to 1.528 x 10^4 then it is in standard form.
2.3010 to the 4th power in standard notation is 28.032799749201
The standard notation of 7.86x10 to the power of -4 is 0.000786
