express the numbers in decimal notations 2.24 x 10 -5
2.24 x 10^(-5)
note that since the exponent of 10 is negative (which is -5), we just move the decimal point 5 places to the LEFT, or:
0.0000224
hope this helps~ :)
To express the number in decimal notation, we first need to understand the concept of scientific notation. Scientific notation is a way of expressing numbers that are either very large or very small in a concise and standardized format.
In scientific notation, the number is expressed as the product of a coefficient and a power of 10. The coefficient is a number greater than or equal to 1 but less than 10, and the power of 10 represents how many places the decimal point needs to be shifted.
Given the number 2.24 x 10^(-5), we can express it in decimal notation by evaluating the expression.
First, we take the coefficient, which is 2.24, and then we move the decimal point to the left by the number specified by the power of 10, which is -5. Since the power is negative, we move the decimal point to the left.
Starting with 2.24, we move the decimal point 5 places to the left.
2.24 becomes 0.0000224.
Therefore, the number 2.24 x 10^(-5) in decimal notation is 0.0000224.
