Which of the following is not a perfect cube ?
The cube of 4 is _______________.
The value of 5^{3 }is __________.
The cube of an even number is always ____________.
The cube of an odd number is always __________.
Each prime factor appears _________ times in its cube?
Which of the following is HardyRamanujan Number ?
By which smallest natural number 392 must be multiplied so as to make the product a perfect cube ?
392 = 2 × 2 × 2 × 7 × 7
Hence the number should be multiplied by 7 to make it a perfect cube.
The smallest natural number by which 243 must be multiplied to make the product a perfect cube is __________.
The smallest natural number by which 704 must be divided to obtain a perfect cube is
The smallest natural number by which 135 must be divided to obtain a perfect cube is
we have 135 = 3 x 3 x 3 x 5
Grouping the prime factors of 135 into triples, we are left over with 5.
∴ 135 is not a perfect cube
Now, [135]divided by5 = [ 3 x 3 x 3 x 5] divided by5
or 27 = 3 x 3 x 3
i.e. 27 is a perfect cube.
Thus, the required smallest number is 5
Which of the following is not a perfect cube ?
The expansion of a^{3} is ___________.
What will be the unit digit of the cube of a number ending with 2 ?
What will be the unit digit of the cube of a number ending with 4 ?
What will be the unit digit of the cube of a number ending with 6 ?
A cuboid has dimensions 5cm, 2cm, 5cm. How many such cuboid will be needed to form a cube ?
Given, sides of a cuboid are 5cm, 2cm and 5cm
Volume of cuboid =5*2*5 = 50 cm3
Let the side of the cube formed with
minimum number of cuboids = x
Hence volume of the cube = x3
Number of cuboids required = n
Hence n*50 = x3
Now, n*50 must be perfect cube
n*50 = n*2*5*5
So, minimum value of n = 2*2*5 = 20
Hence, the number of cuboid will be
needed to form a cube is 20
How many cuboids of dimensions 15cm, 30cm,15cm will be needed to form a cube ?
729 is the value of _______________.
Which of the following is a perfect cube ?
What is the volume of a cube whose edge is 2cm ?
The symbol for cube root is __________.
The cube root of 512 is ________.
The value of ∛343 is
Which of the following is true for any natural number n?
Take any natural number(except 1). This identity would hold for any natural number.
Natural numbers are 1,2,3,4,5____ upto infinity with all positive terms.
If the volume of a cube is 125 cm^{3} then what would be the length of its side?
What will be the unit digit of the cube root of a number ends with 8?
What will be the unit digit of the cube root of a number ends with 2?
What will be the unit digit of the cube root of a number ends with 3?
What will be the unit digit of the cube root of a number ends with 7?
9 is the cube root of __________.
9 is the cube root of 729 because 9 x 9 x 9 = 729
So option B is correct answer.
The number of digits in the cube root of a 6digit number is _______.
As 100^{3 }= 1000000 which is the smallest 3 digit number. So it’s only 2 digit number which is the cube root of a 6 digit number
How many digits will be there in the cube root of 46656 ?
How many digits will be there in the cube root of 512 ?
What will be the unit digit of ∛15625
If we multiply 5 three times we receive 125 where 5 is at the one’s place. So cube which has 5 at one’s place will have a root which have 5 at one’s place
How many zeros will be there in the cube root of 27000?
How many zeros will be there in the cube root of 800?
Since in cubes the zeros become triple ,for instance 10*10*10=1000, a number with two zeros does not have a cube root.
If 7^{3 }= 343, then ∛343 = _________.
If 8^{3 }= 512, then ∛512 = _______
8*8*8 =512
What will be the unit digit of ∛216
