Question

Find the value of $\left|-4\right|.\left|3\right|.$

(A) -12

(B) -1

(C) 7

(D) 12

Short answer

The value of $\left|-4\right|.\left|3\right|$is 12.

Step-by-step solution

– Concept of modulus

The modulusfunction gives the absolute value of a number irrespective of the number’s sign. It always gives a non-negative value of any number or variable. It is denoted by $\left|x\right|.$

– Expand the modulus

$\begin{array}{c}\left|-4\right|.\left|3\right|=-(-4)\cdot 3\\ =4\cdot 3\end{array}$

– Multiply the numbers

$\begin{array}{c}4\cdot 3=4\times 3\\ =12\end{array}$
