Question

How many perfect square are there between 1,000,000 and 9,000,000?​

Answer 1

Answer: 1999 perfect squares between 1,000,000 and 9,000,00

Step-by-step explanation:

Sq root of 1,000,000 is 1000 and square root of 9,000,000 is 3000

Hence there are squares of 1001 to 2999 I. e. 1999 perfect squares between 1,000,000 and 9,000,00

Answer 2

Answer:

1999

Step-by-step explanation:

The square root of 1,000,000 = 1,000.

The square root of 9,000,000 = 3,000.

This means that the number of perfect square will be every number from 1,000^2 to 3,000^2. To find how many numbers that is, just do 3000-1000 = 2000, and then subtract one because otherwise you would be counting the 3000^2 which you don't want to do (it asks how many perfect squares are between the two numbers).

2000 - 1 = 1999.
