3(15−9)2 + 2 ⋅ 5
3(15−9)2 + 2 ⋅ 5
First, we simplify the expression within the parentheses:
15 - 9 = 6
Now we substitute the simplified expression back into the original equation:
3(6)2 + 2 ⋅ 5
Next, we perform the multiplication inside the parentheses:
6^2 = 36
Now we substitute the value back into the equation:
3(36) + 2 ⋅ 5
Next, we perform the multiplication:
3 * 36 = 108
2 * 5 = 10
Now we substitute the values back into the equation:
108 + 10
Finally, we add the numbers together:
108 + 10 = 118
Therefore, the value of the expression 3(15−9)2 + 2 ⋅ 5 is 118.
To simplify the expression 3(15−9)2 + 2 ⋅ 5, follow these steps:
Step 1: Simplify the parentheses.
15 - 9 = 6
Step 2: Multiply the result from Step 1 by 3.
6 * 3 = 18
Step 3: Square the result from Step 2.
18^2 = 324
Step 4: Multiply 2 by 5.
2 * 5 = 10
Step 5: Add the results of Steps 3 and 4.
324 + 10 = 334
Therefore, the simplified form of the expression is 334.
To simplify the expression 3(15−9)2 + 2 ⋅ 5, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Let's break down the expression step by step:
1. Start by simplifying what's inside the parentheses: 15 − 9 = 6.
The expression now becomes 3(6)2 + 2 ⋅ 5.
2. Next, solve the exponent: 6^2 = 36.
The expression simplifies further to 3(36) + 2 ⋅ 5.
3. Proceed to perform the multiplication: 3 × 36 = 108 and 2 × 5 = 10.
The expression now becomes 108 + 10.
4. Finally, perform the addition: 108 + 10 = 118.
So, the simplified value of 3(15−9)2 + 2 ⋅ 5 is 118.
