Express the number 0.05 in scientific notation.
0.05 can be expressed in scientific notation as 5 x 10^-2.
To express the number 0.05 in scientific notation, you need to write it as a number between 1 and 10, multiplying by the appropriate power of 10.
In this case, 0.05 can be rewritten as 5 times 10 raised to the power of -2.
So, in scientific notation, 0.05 is written as 5 × 10^-2.
To express a number in scientific notation, we want to write it in the form "a × 10^b," where "a" is a value between 1 and 10 (inclusive) and "b" is an integer representing the appropriate power of 10.
To express the number 0.05 in scientific notation, we need to move the decimal point to the right until there is only one non-zero digit to the left of the decimal point.
Starting with 0.05, we will move the decimal point two places to the right to get 5.0. Remember, moving a decimal point to the right increases the power of 10 by the number of places moved.
Now, we have 5.0, which can be written as 5.0 × 10^(-1). The value 5.0 is between 1 and 10, and we moved the decimal point two places to the right, so the exponent is -2.
Therefore, the number 0.05 in scientific notation is 5.0 × 10^(-2).
