Step-by-step explanation:
2/root 9=2/3 = 0.6666666667
Answer:
The correct answer is third option
√5/(x²y)
Step-by-step explanation:
It is given an expression,√(55x⁷y⁶/11x¹¹y⁸)
Points to remember
Identities
xᵃ/xᵇ = x⁽ᵃ ⁻ ᵇ)
x⁻ⁿ = x¹/ⁿ
<u>To find the equivalent expression</u>
We have, √(55x⁷y⁶/11x¹¹y⁸)
By using above identity we can write,
√(55x⁷y⁶/11x¹¹y⁸) = √[(55/11) (x⁷/x¹¹) (y⁶/y⁸)]
= √[5x⁷⁻¹¹ y⁶⁻⁸]
= √[5x⁻⁴ y⁻²]
= √[5/x⁴y²]
= √5/(x²y)
Therefore the correct answer is third option
√5/(x²y)
Answer:
x=12
Step-by-step explanation:
4x+6y=60 y=2
4x+6(2)=60
4x+12=60
4x=60-12
4x=48
x=
x=12
The extraneous solution of the given radical equation is x = 3
<h3>
Finding the extraneous solution:</h3>
Here we have the radical equation:

We want to get the extraneous solution, to get it, we first need to square both sides of the equation, so we get:

Now we got a quadratic equation, we can rewrite it as:

To solve this we use Bhaskara's formula, we will get:

Then the two solutions are:
x = (15 + 9)/2 = 12
x = (15 - 9)/2 = 3
<h3>Which one is the extraneous solution?</h3>
Let's evaluate both solutions in our original equation and let's see which is the one that does not work:
for x = 12 we have:

This is true.
For x = 3 we have:

This is false, so the extraneous solution is x = 3.
