Answer: The value of the incorrect expression is 17.2 and the correct expression is 34.4.

Explanation:

The BODMAS rule is followed t solve the expressions.Where B=Bracket, O=Of, D=Division, M=Multiplication, A=Addition and S=Subtraction.

The given expression is,

[tex](7\times 3.4)-[(2.8\times 5)-(4.3\times 2)]+16[/tex]

First solve the parenthesis,

[tex]23.8-[14-8.6]+16[/tex]

Now solve the brackets,

[tex]23.8-5.4+16[/tex]

[tex]39.8-5.4=34.4[/tex]

If the given expression does not have brackets and parenthesis.

[tex]7\times 3.4-2.8\times 5-4.3\times 2+16[/tex]

[tex]23.8-14-8.6+16[/tex]

[tex]39.8-14-8.6[/tex]

[tex]39.8-22.6=17.2[/tex]

Therefore, the correct value of the expression is 34.2 and the incorrect value of the expression is 17.2.
