Question

3•(7+2)-5•3=. 2•6+3•8=

Answer 1

3 * (7 + 2) - 5 * 3 = 27 - 15 = 12
2 * 6 + 3 * 8 = 12 + 24 = 36

Answer 2

3*(7+2)-5*3=12           2*6+3*8=36

Answer 3

Let's solve the given expressions step by step:

1. 3 • (7 + 2) - 5 • 3: First, perform the operations inside the parentheses: 3 • (7 + 2) = 3 • 9 = 27 Next, perform the multiplication outside the parentheses: 27 - 5 • 3 = 27 - 15 = 12

   So, 3 • (7 + 2) - 5 • 3 = 12.

2. 2 • 6 + 3 • 8: Perform the multiplications first: 2 • 6 = 12 3 • 8 = 24

   Then, add the results: 12 + 24 = 36

   So, 2 • 6 + 3 • 8 = 36.

Therefore, the solutions are:

1. 3 • (7 + 2) - 5 • 3 = 12
2. 2 • 6 + 3 • 8 = 36
