Add 2–8√+3–8√ .(1 point)
The given expression is 2–8√+3–8√.
To simplify the expression, we combine like terms. The terms 2 and 3 are like terms because they both have no square root. Similarly, the terms -8√ and -8√ are like terms because they both have the square root of 8.
So we have:
2-8√+3-8√ = (2+3) + (-8√-8√)
Simplifying the terms without the square root:
= 5 + (-16√)
Now combining like terms:
= 5 - 16√
So the simplified expression is 5 - 16√.
To add 2–8√+3–8√, we can simplify like terms.
First, let's group the terms with the square root together.
So, we have (2 – 8√) + (3 – 8√).
Now, we can combine the constants (the numbers without a square root) and the terms with the square root separately.
The sum of 2 and 3 is 5.
The terms with the square root, –8√ and –8√, can be combined to give –16√.
Therefore, the final answer is 5 – 16√.
To add the given expression, 2–8√+3–8√, we can simplify it by combining like terms.
We have two terms with a square root of 8, so we can combine those first: -8√ + (-8√) = -16√.
Now we can combine the constant terms: 2 + 3 = 5.
So the simplified expression is 5 – 16√.
