Question

Help I really want a good grade.

Answer 1

So for this expression, remember PEMDAS

• Parentheses
• Exponents
• Multiplication and Division
• Addition and Subtraction

Firstly, start with solving inside the parentheses: $2^3-6+9$

Next, solve the exponent: $8-6+9$

Now that we only have addition and subtraction, solve it from left to right to get your answer:

$8-6+9 \\ 2+9 \\ 11$

Your answer is 11.

Answer 2

Hey there!

In order for you to solve this equation to make it easier to solve , you need to do, PEMDAS

Which contains...

$Parentheses \\ \\ Exponents \\ \\ Multiplication \\ \\ Division \\ \\ Addition \\ \\ Subtraction$

Solving your equation

$2^3 -( \frac{30}{5})+ 9 \\ \\ 2^3 = 8\\ \\ 8 - \frac{30}{5} + 9\\ \\\frac{30}{5} = 6 \\ \\ 8 - 6 + 9 \\ \\ 8-6 = 2 \\ \\ 2 + 9 = 11 \\ \\ \\ \\ \\ Answer: 11$

Good luck on your assignment and enjoy your day!
