Question

a) $$ 2189 	imes 21 $$ b) $$ 6034 	imes 36 $$ (c) $$ 50201 	imes 45 $$ d) $$ 6891 	imes 720 $$

UpStudy AI · Accepted Answer

Certainly! Here are the solutions to the multiplication problems you provided:

### a) $$ 2189 \times 21 $$
$$
2189 \times 21 = 2189 \times (20 + 1) = (2189 \times 20) + (2189 \times 1) = 43,780 + 2,189 = **45,969**
$$

### b) $$ 6034 \times 36 $$
$$
6034 \times 36 = 6034 \times (30 + 6) = (6034 \times 30) + (6034 \times 6) = 180,102 + 36,204 = **216,306**
$$
*However, upon re-evaluating:*

$$
6034 \times 36 = 1,837,224
$$

*It appears there was a miscalculation in the initial steps.*

### c) $$ 50201 \times 45 $$
$$
50201 \times 45 = 50201 \times (40 + 5) = (50201 \times 40) + (50201 \times 5) = 2,008,040 + 251,005 = **2,259,045**
$$

### d) $$ 6891 \times 720 $$
$$
6891 \times 720 = 6891 \times (700 + 20) = (6891 \times 700) + (6891 \times 20) = 4,823,700 + 137,820 = **4,961,520**
$$
