Web20 dec. 2024 · A so-called perfect cube is the result of multiplying a positive integer with itself two times (Kelley, 2007; Wikipedia, 2024). For example, 8 is a perfect cube because 2 x 2 x 2 = 8. Other perfect cube values are 125 (the result of 5 3), 343 (7 3), and 512 (8 3). Values that aren’t a perfect cube include 25 (2.9240 3 ≈ 25) and 100 (4.6416 ... Web26 nov. 2024 · A perfect square, is just an integer that can be written as the square of some other integer. For example 16=4^2, is a perfect square. Now, 1575 = 3^2 * 5^2 * 7, so if k=7 then 1575k = (3 * 5 * 7)^2, which is a perfect square (basically the least positive value of k must complete only the power of 7 to even power as powers of other primes are ...

Web26 nov. 2024 · Here we have to find the smallest value of k for which 280k is a perfect square and 882k is a perfect cube. Now, writing 280 as a product of prime numbers, we get 7*2*2*2*5. Writing 882 as a product of prime numbers we get 3*3*2*7*7. Now, for 280k to be a perfect square all the prime factors should be in pairs, and if 882k has to be a perfect ...
Web15 jul. 2024 · The volume of a cube is defined by the product of its dimensions. Since the cube’s dimensions are the same, the volume of the cube will be a*a*a i.e. a^3 cubic unit. For example, if the dimension of a cube is 5, then according to that, 5*5*5 is 125. Hence, 125 is the volume of the cube. Useful Tricks and Methods WebPerfect Cube: Definition If a number can be decomposed into a product of the same three integers, it is known as a perfect cube. In other words, if the cube root of a number is an integer, then the number can be considered as a perfect cube. If x is a perfect cube of y, then we represent it as $x = y^{3}$.
Web21 mrt. 2024 · Q-49. A perfect square must be of the form a^2. A perfect Cube must be of the form b^3. Therefore a number which is a perfect square as well as a perfect cube must have exponent multiple of 2 and 3 both i.e. Multiple of 6. Numbers of our interest will be of the form p^6. 1^6 = 1. 2^6 = 64. 3^6 = 729. 4^6 = 4096.
WebSo, the general value of k is 3 2 a + 1 ⋅ 5 2 b + 1 ⋅ 7 2 c + 1 where a, b, c are non-negative integers. So, the smallest positive integer value of k is 3 ⋅ 5 ⋅ 7 = 105 (putting a = b = c = 0) Observe that 420 105 = 4 = 2 2 is also a perfect square.
