Question
ype the correct answer in the box. Use numbers instead of words.An expression is shown.2โข(๐คโ๐ฅ+๐ฆ)2What is the value of the expression forย ๐ค=โ1,ย ๐ฅ=โ2, andย ๐ฆ=3?ย The value of the expression isย .
Solution
First, substitute the given values into the expression.
So, 2โข(๐คโ๐ฅ+๐ฆ)2 becomes 2โข((-1) - (-2) + 3)2
Simplify the expression inside the parentheses first.
-1 - (-2) + 3 equals -1 + 2 + 3, which is 4.
So, the expression becomes 2 * (4)2
Then, square the value inside the parentheses.
4 squared is 16.
So, the expression becomes 2 * 16.
Finally, multiply 2 by 16 to get 32.
So, the value of the expression for ๐ค=โ1, ๐ฅ=โ2, and ๐ฆ=3 is 32.
