Question
Simpliry $754 \times 845 + 754 \times 155$ by using distributivity of multiplication over addition.
✓
Answer
Distributive law of multiplication over addition: $a (b + c) = a \times b + a \times c$
$\therefore 754 \times 845 + 754 \times 155$
$= 754(845 + 155)$
$= 754 \times 1000 = 754000$
Hence, $754 \times 845 + 754 \times 155 = 754000.$
$\therefore 754 \times 845 + 754 \times 155$
$= 754(845 + 155)$
$= 754 \times 1000 = 754000$
Hence, $754 \times 845 + 754 \times 155 = 754000.$
