0.0000009 can be expressed as 9 x 10^-7 in scientific notation.
Nothing is measured in scientific notation. Scientific notation is used merely to represent the result of some measurement - especially when that outcome is a very small or a very large number.
It is 2.046*10^7
The result of multiplying 1,000,000,000,000,000,000,000,000 by 115 is 115,000,000,000,000,000,000,000,000. This can also be expressed in scientific notation as 1.15 × 10^27.
No reason to put it in scientific notation but the result would be 2.59 x 10^4

There is no reason to put it in scientific notation. However, the result would be 3.158697 x 10^6
When adding or subtracting numbers in scientific notation, the exponents must be the same to ensure that the terms are expressed in the same scale. Scientific notation represents numbers as a product of a coefficient and a power of ten, so if the exponents differ, the values are on different scales, making direct addition or subtraction impossible. By adjusting the numbers to have the same exponent, you can accurately combine the coefficients before simplifying the result back into proper scientific notation.
The result is: 3.1 x 10^5
You have already expressed it in standard notation. However, in standard form the result is: 1.175 × 10-1
(6.2*10^4) * (3.3*10^2) = 20.46*10^6 = 2.046*10^7.
The result is: 9.19263177 x 10^9
Move 4 decimal places to the right, so the exponent for base 10 is negative. Therefore, the result in scientific notation is 1.023 x 10-4
