Describe how to evaluate the expression 3^2 + (21 - 9) X 6÷2. Can someone help me out, please? I'm having trouble, and my teache
mylen [45]

Answer:

3^2+\left(21-9\right)\times \:6\div \:2=45

Step-by-step explanation:

Given the expression

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

Follow the PEMDAS order of operations

3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2

calculate within parentheses  \:(21-9)=12

=3^2+12\times \:6\div \:2

calculate exponents  3^2=9

=9+12\times \:6\div \:2

Multiply and divide (left to right)

=9+36

Add and subtract (left to right)  12\times \:\:6\div \:\:2=36

=45

Thus,

3^2+\left(21-9\right)\times \:6\div \:2=45
