Question

simplify the expression √8y + 5 √50y - 2 √18y
Answer
its incorrect i think maybe there is a number missing before √(2y)
Answer
the answer choices are:
a. 13√2y
b. 21√2y
c. (√8y + 5 √50y - 2 √18)√y
d. 882y
Answer
5√(2y). isnt part of the answer choice its wrong
Answer
i think im just gonna guess :(

To simplify the given expression, we first need to simplify the square roots.

√8y = √(4 * 2y) = √4 * √(2y) = 2√(2y)

√50y = √(25 * 2y) = √25 * √(2y) = 5√(2y)

√18y = √(9 * 2y) = √9 * √(2y) = 3√(2y)

Now, substituting the simplified square roots back into the given expression, we have:

2√(2y) + 5√(2y) - 2(3√(2y))

Combining like terms, we get:

(2 + 5 - 6)√(2y)

Simplifying further, we have:

1√(2y) = √(2y)

Therefore, the simplified expression is √(2y).

I apologize for the mistake. Let's go through the simplification process again.

√8y can be simplified as √(4 * 2y) = 2√(2y)

√50y can be simplified as √(25 * 2y) = 5√(2y)

√18y can be simplified as √(9 * 2y) = 3√(2y)

Plugging these simplified forms back into the expression, we have:

2√(2y) + 5√(2y) - 2√(2y)

Combining like terms, we get:

(2 + 5 - 2)√(2y) = 5√(2y)

Therefore, the simplified expression is 5√(2y).

Apologies for the confusion. Let's simplify the expression once again:

2√(2y) + 5√(2y) - 2√(2y)

Combining like terms, we get:

(2 + 5 - 2)√(2y) = 5√(2y)

So, the correct answer is 5√(2y).

Plugging these simplified forms back into the expression, we have:

2√(2y) + 5√(2y) - 2√(2y)

The like terms cancel out, leaving us with:

0

Therefore, the simplified expression is 0.
