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)
So find factors of 5
1 and 5
both factors must be both negative or both positive to be positive 5
adds to negative 4
to do that, they both must be negative
-5 times -1=5
-5+-1=-6
doesn't work
the only way it would work is if it is what multipies to -5 and adds to -4 which then the numbers would be -5 and 1
Answer:
Q ' (3,4)
Step-by-step explanation:
When we reflect across the x axis, the y coordinate becomes -y
Q (3,-4) becomes Q' (3,- -4)
Q ' (3,4)
3x+5=19
-5 -5
3x=14
/3 /3
x= 4 2/3
