Question

347•(43+78)=? (66+89-111-3)•2=?​

Answer 1

347•(43+78)=41987

347*121=41987

(66+89-111-3)•2=82

41*2=82

Answer 2

Пошаговое объяснение:

347 * (43 + 78) = 347 * 121 = 41987

(66 + 89 - 111 - 3) * 2 = 41 * 2 = 82

Answer 3

Let's solve these equations step by step:

1. 347 • (43 + 78) First, add the numbers inside the parentheses: 43 + 78 = 121

   Now, multiply 347 by 121: 347 • 121 = 41,887

So, 347 • (43 + 78) = 41,887.

2. (66 + 89 - 111 - 3) • 2 First, perform the operations inside the parentheses: 66 + 89 - 111 - 3 = 141 - 111 - 3

   Now, continue with the subtraction: 141 - 111 - 3 = 30 - 3

   Finally, multiply the result by 2: (30 - 3) • 2 = 27 • 2 = 54

So, (66 + 89 - 111 - 3) • 2 = 54.
