Verify a÷(b +c)=(a÷b)+(ca÷c) when a =10 b =5 and c=-2 ​

Answer» ONG>Given
  • To VERIFY a÷(b+c) = (a÷b) + (ca÷c)
  • a = 10
  • b = 5
  • c = - 2

Solution

a \div (b + c) = ( a\div b ) + (ca \div c) \\ 10 \div (5 - 2) = (10 \div 5) + ( ( - 2)(10) \div ( - 2)) \\ \frac{10}{3} = \frac{10}{5} + \frac{( - 2)(10)}{( - 2)} \\ \frac{10}{3} = 2 + 10 \\ \frac{10}{3} = 12

10/3≠12

Therefore a÷(b+c) ≠ (a÷b) + (ca÷c)
