Question

Find the least number which must be subtracted from 0.00032 6 to get a perfect square also find the square root of that number ​

Answer 1

Answer:

2 must be subracted

Step-by-step explanation:

0.000326=0.018×0.018+2

perfect square = 0.000324

square root = 0.018

Answer 2

Given,

The number 0.000326.

To Find,

the least number which should be subtracted to get a perfect square number.

Also the square root of the number.

Solution,

If we can write the decimal form of the number in fraction form we get,

0.000326 =$\frac{326}{1000000}$.

Now the number 326 is situated between 324 and 361.

More precisely we can say, $18^{2}\leq 326\leq 19^{2}$.

Also $18^{2}$=324.

Also $\sqrt{\frac{324}{1000000} }$=$\sqrt{(\frac{18}{1000} )^{2} }$=$\frac{18}{1000}$=0.018.

∴The least number which should be subtracted from 0.000326 to get a perfect square number is  0.000326-0.000324=0.000002.

Hence, the least number to substracted from the given one to get the perfect square is 0.000002. The square root of the number is 0.018.
