Chapter 2: Q4. (page 73)

Evaluate the expression using the distributive property and mental math.
$6 (103)$

Short Answer

Expert verified

$6 (103) = 618$ .

Step by step solution

Step-1 – What are real numbers?

Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

Step-2 – Distributive Property of Multiplication

Suppose a, b, and c is three real numbers.

Distributive Property of Multiplication

Property: $a (b + c) = a \cdot b + a \cdot c$

Example: $12 (3 + 4) = 12 \cdot 3 + 12 \cdot 4 = 36 + 48 = 84$

Step-3: Evaluate the expression using the distributive property and mental math.

We can write 103 as 100+ 3, to evaluate the expression 6(103), we can use the distributive method of multiplication.

Distributive Property of Multiplication

Property: $a (b + c) = a \cdot b + a \cdot c$

\begin{array}{l} 6 (103) = 6 (100 + 3) = 6 \cdot 100 + 6 \cdot 3 = 600 + 18 = 618 \\ 6 (103) = 618 \end{array}
