Answer 1

Answer:

308

Step-by-step explanation:

11×4×7 = 308

11× (4×7) = 11×28 = 308

(11×4)×7 = 44×7 = 308

Answer 2

b) 11 × 4×7

१. 11× 4× 7= 44× 7= 308

२. 11× ( 4×7) = 11× 28= 308

३. (11×7)×4= 77× 4=308

c) 14* 9*3

१. 14*9*3= 126*3= 378

२. 14*(9*3)= 14*27= 378

३. (14*3) *9= 42*9= 378

3.b) (11 + 8) X 7

(11 + 8) X 7= 11× 7+ 8×7= 77+56= 133

c) 4 X (23+5)

4 X (23+5)= 4×23+4×5=92+20=112

d) (15 + 6) X 6

(15 + 6) X 6= 15×6+6×6= 90+ 36= 226.
