-0.0226051 expressed in scientific notation.
-0.0226051 expressed in scientific notation is -2.26051 x 10^-2
To express -0.0226051 in scientific notation, we move the decimal point to after the first non-zero digit and multiply it by 10 raised to the appropriate exponent.
In this case, the first non-zero digit is 2. Moving the decimal point, we get 2.26051.
To get the exponent, count the number of places we moved the decimal point. In this case, we moved it 3 places to the right.
Therefore, -0.0226051 in scientific notation is expressed as -2.26051 x 10^-2.
To express a number in scientific notation, you need to represent it in the form of a × 10^b, where "a" is a number greater than or equal to 1 but less than 10, and "b" is an integer that represents the power of 10.
To convert the number -0.0226051 into scientific notation, follow these steps:
Step 1: Determine the value of "a":
-0.0226051 is a decimal number between -1 and 0. To express it in the desired form, we need to move the decimal point to the right until we have a number between 1 and 10.
In this case, we move the decimal point four places to the right: 0.000226051.
Step 2: Determine the value of "b":
The number of times you have moved the decimal point to the right gives you the exponent "b". In this case, since we moved it four places, b will be -4.
Step 3: Write the expression in scientific notation:
Putting it all together, we get: -0.0226051 = -2.26051 × 10^-2.
So, -0.0226051 expressed in scientific notation is -2.26051 × 10^-2.
