Fourfifth of oneeighth of 3/4^{th} of A is 64. What is the cube root of 3/5^{th} of A?
Find the least number that must be subtracted from 5607 so as to get a perfect square.
Square of 75 is 5625 square of 74 is 5476 so use must get 5476
5607  x is 5476
x is 131
Square root of 5476 is 74
What will be the number of zeros in the square of 60?
The square of 60 is 3600. Therefore, the number of zeroes is 2.
How many natural numbers lie between 9^{2} and 10^{2}?
Between 9^{2} and 10^{2}
Here, n = 9 and n + 1 = 10
∴ Natural number between 9^{2} and 10^{2} are (2 × n) or 2 x 9, i.e. 18.
(401)^{2 }= 1600+180 = 1521
Without adding, find the sum. 1 + 3 + 5 + 7 + 9 + 11 + 13
Total consecutive odd numbers (n) = 7
We know that, Sum = n^{2}
= 7^{2}
= 49
Hence, the correct answer is 49
The square root of 729 is 27.
Sum of squares of two numbers is 145. If square root of one number is 3, find the other number.
If a number has 1 or 9 in the unit’s place, then it’s square ends in ________.
If a number has 1 or 9 in the unit’s place, then it’s square ends in 1
None of the square numbers end with _________ at unit’s place.
According to the Property 1, A number having 2, 3, 7 or 8 at it's unit's place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8.
The inverse of squaring a number is square root.
Find the perfect square numbers between 50 and 60.
Since we have 72=49 and 82=64.There is no perfect square between 50 and 60.
What is the least perfect square which is divisible by 2, 4 and 6?
LCM of 2,4,6= 2×1×2×3=12
Least perfect square which is a multiple of 12 is 36.
2025 plants are to be planted in a garden in such a way that each row contains as many plants as the number of rows. Find the number of plants in each row.
Let the number of rows be x
Thus, the each row contains x plants.
The total number of plants in the garden = number of rows × number of plants in each rows
Thus,
2025=x×x
=>x^{2 }=2025
=>x= 3×3×3×3×5×5
=3×3×5
=45
Thus, there are 45 rows and each row contains 45 plants.
Find the greatest 4digit number which is a perfect square.
By division method we find the root of 9999 and we get the remainder 198.So subtracting 198 from 9999 we get 9801 as the greatest 4digit perfect square.
What will be the number of zeros in the square of 400?
Square of 400 = 160000
Hence, the number of zeroes is 4
What is smallest number with which 5400 may be multiplied so that the product is perfect cube?
∛(5400 x 5) = 30
The square of 7 is the largest number between 4 to 50.
Without adding,find the sum of 1+3+5+7+9+11+13+15+17+19
Total consecutive odd numbers = 10
Thus n = 10
Therefore sum = n × n
= 10× 10 = 100
Square root of 529 is 23
