Find the smallest number by which 1375 must be divided so that the quotient is a perfect cube
Only non-perfect cube in previous question was = 243 Show
(a) Multiplied so that the product is a perfect cube. Firstly let us find the prime factors of 243 243 = 3 × 3 × 3 × 3 × 3 = 33 × 32 Hence, to make it a perfect cube we should multiply it by 3. (b) Divided so that the quotient is a perfect cube. Firstly let us find the prime factors of 243 243 = 3 × 3 × 3 × 3 × 3 = 33 × 32 Hence, to make it a perfect cube we have to divide it by 9. Find the smallest number by which 10368 be divided so that the result is a perfect square. Also find the square root of the resulting number.Nội dung chính Nội dung chính
Answer VerifiedHint: In this problem, we have to find the smallest number by which 10368 be divided so that the result is a perfect square. Also find the square root of the resulting number. We can first find the smallest number, which is divided to 10368 to give the resulting perfect square. We can then find the square root of the resulting perfect square. Complete step by step solution: Note: Students make mistakes while finding the value of the smallest number by which the given number when divided, gives a perfect square, here we can use the LCM method to find the smallest number in an easier manner. We can take LCM to find the square root of the perfect square number.

To do: To find the smallest number by which 6912 must be divided so that the number formed is a perfect cube. Therefore, we should divide 6912 by 22=4 2 2 = 4 , the smallest number to get 1728 which is a cube of 12 . What is the smallest number by which 3584 must be divided so that the quotient obtained is a perfect cube also find the cube root of the perfect cube so obtained?Thus,the least number to be divided to form a perfect cube is 7. The perfect cube obtained is 3584/7=512. What is the smallest number by which 8788 must be divided so that the quotient is a perfect cube?So, 2 × 2 = 4 is the least number by which 8788 should be divided so that the quotient is a perfect cube. What is the smallest number by which 1375 should be divided so that the quotient may be perfect cube?So, clearly 1375 should be divided by 11 to make it a perfect cube. What is the smallest number by which 6912 must be divided so that the result is a perfect cube?Given: A number 6912 . To do: To find the smallest number by which 6912 must be divided so that the number formed is a perfect cube. Therefore, we should divide 6912 by 22=4 2 2 = 4 , the smallest number to get 1728 which is a cube of 12 . Is 6912 a perfect cube?If we look at the number 6912, we know that the cube root is 19.048812623618, and since this is not a whole number, we also know that 6912 is not a perfect cube. What is the smallest number by which 6912 must be multiplied so 5 that the product is a perfect cube?The given number is 6912. Clearly, 4 is the only number left after forming the cube groups of prime factors. Hence, 4 is the smallest number by which 6912 must be divided so that the quotient obtained will have a perfect cube root. What is the smallest number by which 8575 must be divided so that the quotient is a perfect cube?Answer: The smallest number by which 8575 must be multiplied so that the product is a perfect cube is 5. What is the smallest number 1375 should have?Answer: 11 is the number which should be multiplied with 1375 to make it a perfect cube.
What is the smallest number by which 1323 may be multipled the product is a perfect cube so that?Hence, the smallest number by which 1323 must be multiplied to obtain a perfect cube is 7.
Is 13720 a perfect cube?25 is the smallest number by which 13720 must be multiplied to obtain a perfect cube. i.e. 13720×25 = 343,000 is a perfect cube.
