Q. Use the order of operations to solve the expression.−32+(−4)2+21(8)
Apply PEMDAS: Apply the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right), often abbreviated as PEMDAS.First, we evaluate the exponents.−32=−9 (since the negative sign is not raised to the power, only the 3 is squared)(−4)2=16 (since the negative sign is inside the parentheses, it is squared along with the 4)
Evaluate Exponents: Next, we perform the multiplication.(1)/(2)(8)=1/16 (since 1/2 multiplied by 8 equals 1/16)
Perform Multiplication: Now, we add and subtract the results from the previous steps.−9+16+161First, we add −9 and 16, which gives us 7.7+161
Add and Subtract: Finally, we add the fractions" target="_blank" class="backlink">fraction 161 to the whole number7. To do this, we can convert 7 to a fraction with the same denominator as 161, which is 16. 7=7×(1616)=16112 Now, we add the two fractions. 16112+161=16113
