Answer:
Question 3: 93 Question 4: -18
Explanation:
Use Order of Operations (BEDMAS - Brackets Exponents Division Multiplication Addition and Subtraction).
Question 3:
Start with the numbers inside the brackets.
3^2 (4+6) + 3
= 3^2 (10) + 3
Then, solve the exponents.
= 9 (10) + 3
Multiply 9 and 10.
= 90 + 3
Add the numbers.
= 93
Question 4:
Again, start with the brackets.
3 (4+2) - 6^2
= 3 (6) - 6^2
Then, solve the exponent.
= 3 (6) - 36
Multiply 3 and 6.
= 18 - 36
Subtract the numbers.
= -18 (You can do 36 - 18 which is 18, then add the negative sign)
