Short Answer

Expert verified

(21-11-3)4=28.

Step by step solution

01

Step-1 – What are real numbers? 

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

02

Step-2 – Distributive Property of Multiplication 

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

Distributive Property of Multiplication

Property: a(b+c)=a·b+a·c

Example: 12(3+4)=12·3+12·4=36+48=84

03

Step-3:  Evaluate the expression using the distributive property. 

Distributive Property of Multiplication

Property: a(b+c)=a·b+a·c

(21    11    3  )  4  =  21  ·  4    11  ·  4    3  ·  4  =  84    44    12  =  28(21    11    3  )  4  =  28
