3(15−9)2 + 2 ⋅ 5

1 answer

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.
