Answers
The smallest number by which 1000 should be multiplied so as to get a perfect square is ?
- Smallest number should be multiplied to make 1000 as perfect square
Now,
=> 1000 = 2 × 2 × 2 × 5 × 5 × 5
=> 2² × 5² × 10
=> √(2² ×5² × 2 × 5)
=> 100√10
Hence,
=> 1000 should be multiplied by 10 to get a perfect square.
Answer:
The smallest number by which 1000 should be multiplied so as to get a perfect square = 10
Step-by-step explanation:
Given number is 1000
Required to find the smallest number to be multiplied to get a perfect square
Recall the concept
Perfect squares are numbers that can be expressed and the product of an integer by itself
Solution:
Given number is 1000
The prime factorization of 1000 = 2 × 2 × 2 × 5 × 5 × 5.
Combining we get,
1000 = 2²×5²×2×5
= 10²×10
1000 = 10²×10
In the square root of 1000, we can see that 10 is an integer and is an irrational numbers
Hence, if we multiply 10²×10 by 10
The factorization becomes 10²×10², and the number becomes a perfect square.
Hence,
The smallest number by which 1000 should be multiplied so as to get a perfect square = 10
