Now, these prime factors can be written in the exponential form as, 5 2 × 2 2 How to Write Log in Exponential Form? For example, when we have numbers like 100, we need to find its prime factors and we get 5 × 5 × 2 × 2.
In order to write an expression in exponential form, we need to find the prime factorization of its terms. How to Write an Expression in Exponential Form? For example, if we observe the number 125, it appears to be a usual 3-digit number, but if we write it as 5 3, we know that we are multiplying 5 three times to get 125, or 125 is the third power of 5. It tells us how many times are we actually multiplying a number to get the result. The exponential form is a way of writing numbers using bases and powers. Here, it is important to note that the decimal number written in the standard exponential form will always be greater than 0 and less than 10.įAQs on Exponential Form What is Exponential Form? Step 4: Therefore, the standard exponential form of the number 2030000000000000 is 2.03 × 10 15.The power of 10 was 13 as there were 13 trailing zeros, but now it will become 15. So, we will add 2 to the existing power of 10. For example, in the example written above, if we place a decimal point after 2, then two decimal places will be created in the number 2.03. Step 3: Place a decimal point after the first digit from the left side and add the number of decimal places created to the power of 10.Step 2: Use the beginning of the number and write the digits from the left till the last non-zero digit followed by a 10 raised to power which is equal to the number of trailing zeros.Step 1: Count the number of trailing zeros in the number.To write a number in standard exponential form, we follow the steps given below: It is also known as a scientific notation to write numbers.
For example, it is difficult to make sense of the number 2030000000000000, but it will be easier if we write it in standard form as 2.03 × 10 15. If very large numbers or very small numbers are given, then it is better to use the standard exponential form to represent them.
