Webb6. 4. Which number has a square root between 6 and 7?A. 32B. 36C. 42D. 49 Answer: C. 42. Step-by-step explanation: Let the number N be the number whose square root is between 6 and 7. If 6 and 7 are roots of perfect square, then N is the perfect square of the number between them. To find N, square both given numbers: 6² = (6) × (6) = 36 WebbUse this calculator to find the product of the roots of the equation online.

Webb13 sep. 2024 · Multiplying radicals with the same root. When we multiply two radicals with the same type of root (both square roots, both cube roots, and so on), we simply multiply … WebbThe product of the roots = x 1 · x 2 = (-b + √ (b² - 4ac) )/2a · (-b - √ (b² - 4ac) )/2a = (-b/2a) 2 - ( √ (b 2 - 4ac)/ 2a) 2 ( by a² - b² formula) = b 2 / 4a 2 - (b 2 - 4ac) / 4a 2 = b 2 / 4a 2 - b 2 / 4a 2 + 4ac / 4a 2 = 4ac / 4a 2 = c/a Therefore, the product of the roots of the quadratic equation ax2 + bx + c = 0 is c/a. WebbIn particular, I'll start by factoring the argument, 144, into a product of squares: 144 = 9 × 16. Each of 9 and 16 is a square, so each of these can have its square root pulled out of the radical. The square root of 9 is 3 and the square root of 16 is 4. Then: \sqrt {144\,} = \sqrt {9\times 16\,} 144 = 9×16. income tax rate on corporates
