0.03
Explanation
[tex]\begin{gathered} 0.3^2\colon\lbrack9.8-(5.4+1.4)\rbrack \\ \end{gathered}[/tex]
The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Step 1
Parenthesis
[tex]\begin{gathered} 0.3^2\colon\lbrack9.8-(6.8)\rbrack \\ 0.3^2\colon\lbrack3\rbrack \\ 0.3^2\colon3 \end{gathered}[/tex]
Step 2
Exponents
[tex]\begin{gathered} 0.3^2\colon3 \\ 0.09\colon3 \end{gathered}[/tex]
Step 3
Division
[tex]0.09\colon3=0.03[/tex]
