How many two-digit numbers satisfy this property. : The last digit (unit's digit) of the square of the two-digit number is 8?

Peter had some books in his library. He tried packing them in bags in various ways. While packing 85 books in each bag, 9 bags were not filled completely. Also, while packing 58 books in each bag, 13 bags were not enough to pack all the books. But in the end, he was able to pack the books in M bags, each having M books. How many books did Peter have?

Ana has bought kg of flour. Mary has bought kg of flour and Kristina has bought kg of flour. The one who has bought more flour is

Here the concept of rational numbers was used. The terms were equalized with respect to the denominator and we found that Mary bought maximum flour. The rational numbers were simplifies first to make the terms easier.

Sum of squares of two numbers is 145. If the square root of one number is 3, find the other number.

The irrational number between 2 and 2.5 is

Here we were given the numbers 2 and 2.5 and we were supposed to find which irrational number lies in between them. So we started off with finding the square root of the number and computed which can number can lie in between them, and we found that  lies in between 2 and 2.5.

None of the square numbers end with _________ at unit’s place.

Put the following in order from least to greatest

Here we used the concept of square root, decimal numbers and simplified the numbers first. Then we found out that the correct series is B<C<A which is from smallest to the largest number.

 

Put the following in order from largest to smallest

Here we used the concept of square root, and decimal numbers and simplified the numbers first. Then we found out that the correct series is A<C<B which is from the smallest to the largest number.

Compare and write <, > or =

Here we used the concept of square root. With the help of that we simplified the given terms from both sides using the algebraic formula and then found out the correct sign that needs to be there!  

Which point most closely corresponds to the on the number line below?

What is the approximate value of

So we got the number 12 to find the square root. 12 is not a perfect square so we did a long division method to understand the concept and find out the root. Long division method is explained via text with a reference image. The final answer is 3.464

In between what two integers is the square root of 77?

So in this question we the number 77 was given for which we have to find out in between which numbers its square root is present. So after using the square roots of two numbers we found out that the square root of 77 lies in between 8 and 9 which will be decimal number and not the whole number.
