Concept:
The procedure of obtaining the product of two or more integers is known as multiplication. It is a basic mathematical operation that is frequently utilised in everyday life. When we need to join groups of equivalent size, we employ multiplication.
Given:
The expression (1.9)³-(1.6)³ + (1.6)²+(1.9)²+1.6*1.9*(1.6+1.9).
Find:
The value of the expression.
Solution:
The value of the expression is,
= (1.9)³-(1.6)³ + (1.6)²+(1.9)²+1.6*1.9*(1.6+1.9).
= (1.9)²(1.9+1) - (1.6)²(1.6-1) + 1.6*1.9*(1.6+1.9).
= 3.61*2.9 - 2.56*0.6 + 3.04*3.5
= 10.469 - 1.536 + 10.64
= 19.573.
Hence, the value of the expression is 19.573.
