find the smallest number by which 1100 must be multiplied so that the product becomes a perfect square. Also find the square root of the perfect square so obtained
Answers
Answer:
110
Step-by-step explanation:
By prime factorization method
1100 = 2x2x5x5x11
To be a perfect square, its prime factor should be in pairs.
Hence the smallest number is 11, which we should multiply to get perfect square .
Square root of this perfect square number = 2x5x11 = 110.
ANSWERS≻
✩The smallest Number by which 1100 must be multiplied so that the product is becomes a perfect square = 11 .
The perfect square so obtained by multiplying 1100 and 11 = 12100 .
The Square root of the perfect square so obtained = 110.
✳SOLUTION✳
To find out the smallest number by which 1100 must be multiplied so that the product becomes a perfect square , firstly we must do the factorization of 1100.
1100 = 2 x 2 x 5 x 5 x 11
Here all the factors of the number 1100 except 11 have pairs , so 1100 must be divided by the number 11 to make it a perfect square number .
We are also asked to find the square root of the perfect square so obtained , so for that we must multiply 1100 by 11
1100 × 11 = 12100
So , the perfect square obtained = 12100
Now , we must find the square root of 12100
