write the number 1.4*10^-2 in standerd form
The number 1.4 * 10^(-2) in standard form is written as 0.014.
To write the number 1.4 * 10^(-2) in standard form, follow these steps:
Step 1: Move the decimal point to the right until there is only one non-zero digit to the left of the decimal.
1.4 becomes 14.
Step 2: Count the number of places you moved the decimal point. If you moved it to the right, this value will be positive. If you moved it to the left, it will be negative.
Since we moved the decimal point two places to the left, the exponent will be -2.
Step 3: Write the number in the format a * 10^b, where a is the number with one non-zero digit to the left of the decimal, and b is the exponent from step 2.
In this case, the standard form of 1.4 * 10^(-2) is 0.014.
To write the number 1.4 * 10^-2 in standard form, you need to convert it into a decimal form without any exponent.
Here's how you can do it step by step:
1. Start with the number 1.4.
2. The exponent -2 means that you need to move the decimal point 2 places to the left.
3. Moving the decimal point two places to the left, you get 0.014.
4. Since 0.014 is a decimal number between 0 and 1, you can represent it in standard form without any exponent as 0.014.
Therefore, the number 1.4 * 10^-2 in standard form is 0.014.
