Answer
Find out the evaluate the expression.
42+5⋅32−42÷23 .
To prove
As the expression given in the question be .
= 42+5⋅32−42÷23
Now write the above equation in the form as follows.
[tex]= 42 + 5.32 - \frac{42}{23}[/tex]
As
[tex]\frac{42}{23} = 1.81 (approx)[/tex]
put in the above
= 42 + 5.32 - 1.81
simplify the above
= 47.32 - 1.81
= 45.51
Therefore the evaluate of the 42+5⋅32−42÷23 expression is 45.51 .
