Question

How many zeroes are there in 1 lakh?

Answer 1

Hint: We first find the value of 1 lakh with respect to thousands as we know 1 lakh is equal to 100 thousand. We also use the power value expression to find the number of zeros in 1 lakh.

Complete step by step solution:
We can use the indices or power formula to find the number of zeros in 1 lakh.
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease.
We move the decimal to the smallest one-digit place so that it can be expressed in the multiplication form of 10. For $100000$, we keep moving the decimal to the left. The decimal starts after the last zero in v. We multiply with 10 to compensate for the movement.
We get $100000={{10}^{5}}$. So, the power value gives the solution.
So, the correct answer is “5”.

Note: We express 1 thousand as 1000. We also know that 1 lakh is equal to 100 thousand.Therefore, 1 lakh is equal to $100\times 1000=100000$.We can see that there are 5 zeros in 1 lakh.
