Steps to simplify
[tex]7+3 \cdot (10-6)^2\\7+3 \cdot (4)^2\\7+3 \cdot 16\\7 \cdot 48\\ 55[/tex]
Given :
Jillian simplified the expression [tex]7+3 \cdot (10-6)^2[/tex]
Steps :
[tex]7+3 \cdot (10-6)^2\\7+3 \cdot (4)^2\\7+3 \cdot 16\\10 \cdot 16\\160[/tex]
Explanation
Lets analyze step by step to find out the error.
Use order of operation PEMDAS
Start with parenthesis , exponents , multiply and divide , add and subtract
Jillian simplified the parenthesis first
Second step is correct
Next exponent is simplified
In the fourth step , 7 and 3 are added before multiplication
10 times 16 is not correct
As per PEMDAS, we need to multiply first and then add 7
Error is step [tex]10 \cdot 16[/tex]
[tex]7+3 \cdot 16\\7+ 48\\Add \; 7\\55[/tex]
