Question

Evaluate the expression 4 + 9(3 + 11) - 15 2 using order of operations. the two is a exponet

Answer 1

-95

Explanation:

4+9(3+11)-15²

So, the order of operations is PEMDAS. The first thing is "P" for Parenthesis, so you would do whatever is in the parenthesis first.

3+11= 14

Now, the expression is 4 + 9 (14) - 15²

The next letter is "E" for Exponents. so the 15² has an exponent, so you do 15 x 15.

4+9(14)-225

Next is "M" for Multiplication. A number next to a parenthesis can mean multiplication as well. So, you do 9 × 14 = 126

Now, it's 4 + 126 - 225

Since there is only addition and subtraction left, you go left to right.

4 + 126 = 130

130 - 225 = -95

Hope this helps !!

`\large\textsf{4 + 9(3 + 11) - 15}^\mathsf{2}`

`\large\textsf{3 + 11 = \bf 14}`

`\large\textsf{= 4 + 9(14) - 15}^\mathsf{2}`

`\large\textsf{9(14) = \bf 126}`

`\large\textsf{= 4 + 126 - 15}^\mathsf{2}`

`\large\textsf{= 130 - 225}`

`\large\textsf{= \bf -95}`
