In words, 7500 equals seven thousand five hundred; that is, writing 7500 in words. Let us say that we bought a study table and it cost us 7,500 rupees. Then we would say that the study table we bought is worth seven thousand five hundred rupees. Imagine when the teacher asks us to subtract 500 from 7500. We would answer that five hundred subtracted from seven thousand five hundred is seven thousand.
Numbers that are completely divisible by 2 are called even numbers, and the numbers which are not are odd numbers. Since 7500 is divisible by 2, it is an even number. It is also a composite number since it is even. It is not a perfect square
Any number that can be expressed as the multiplication of any other integer with itself twice is known as a perfect square number.
In the place value system, a digit's placement determines the number's value.
Thousands | Hundreds | Tens | Ones |
7 | 5 | 0 | 0 |
Now, if we look at the table above, we can write 7500 in expanded form. That is
7500=7 \times \text { thousand }+5 \times \text { hundred }+0 \times \text { ten }+0 \times \text { one }
This can also be written as
\begin{aligned}
&=7 \times 1000+5 \times 100+0 \times 10+0 \times 1 \\
&=7500
\end{aligned}
Suppose there are 7500 red beads and 2000 black beads in a box. Our mother asks us how many red beads there are. We would answer by saying there are seven thousand five hundred red beads. Or if we see a sofa, ask the dealer how much it costs. He might say that the sofa is for seven thousand five hundred rupees, or dollars, depending on where we live. Writing 7500 in words or any other number in words becomes useful when writing checks. In cheques, we write the amount we transfer in words followed by the currency. For example, assume we are transferring 7500 rupees to someone. So on the cheque, we write seven thousand five hundred rupees. If it is 7500 dollars, we write seven thousand five hundred dollars. We can see that only the currency changes. The rest remains the same.
You can find out the detailed other number in words article list below:-
Using place values, we can write 7500 in words as seven thousand five hundred.
7000 + 500 = 7500, and seven thousand five hundred is 7500 in words.
The square root of 7500 is given as,
\begin{aligned}
\sqrt{7500} &=\sqrt{(2 \times 2) \times 3 \times(5 \times 5) \times(5 \times 5)} \\
&=2 \times 5 \times 5 \times \sqrt{3} \\
&=50 \sqrt{3} \\
&=86.603
\end{aligned}
A number having only 2 factors, 1 and itself, is known as a prime number. 7500 is not a prime number because it has more than 2 factors like 2, 3, 5, etc.
A number having more than 2 factors is called a composite number. 7500 is a composite number, as 7500 has more than two factors.
