Your answer is wrong, put your answer back into the equation you'd not have squareroot of 8

NwaNimo1:
Square everything.......

then: x+x=8;

2x=8;

therefore x=4

OP please stop reminding me of the money I wasted in school

Verbtips:
sorry oh
how you take square am
whey x no carry ^2,make i mind my biznes sha.
but make i make some tinz clear
i multiply both side with the lcm
which will give you a perfect equation,
and you suppose know say square and square root na enemies them no dey agree.
so the two will eliminate themselves,i guess you go find a math t. To explain the concept better

Oga you don’t know maths
(√x + √x)^2
= (√x + √x) (√x + √x) ✅

But you did ❌
(√x + √x)^2
= x + x

Goan get a math tutor, your math skills sucks

Wrong!

Replace X with 4 and see if you're right🤣

The value of x is 2...na copy I copy d answer from people comment

There's no way I will give you the value of × because my x has no value.

Kai guy you will not kill person

If you know you pass jamb mathematics you should be able to give answer that question easily. My Casio calculator give 2 as the answer anyway.

Answer is √2, no vex na calculator I use. U fit check if I am right. Shikenan!

You have to square both sides twice to completely remove the square roots

x² + x = 64

2x² = 64

2x = 8

x = 4

It is a Surd question.

Solution steps below
Rtx + Rtx=2Rtx (LHS)
Rt8 = Rt4 times Rt 2 (RHS)

Therefore 2Rtx=2Rt2 (because Rt4=2)
Divide both LHS and RHS by 2
Therefore Rtx= Rt2
Therefore x=2
Option a is the answer
N.B Rt= Square root

okay

4

Sq both sides.

X + x = 8
2x=8
X=8/2 = 4

You can check answer with your block Head.


If x =4
Root 4 + root 4 = ?
2 + 2 = 4
Therefore, is 4 not = to square root of 8?
Yes. Root 8 = 4.
So 4=4.

Update;:: my answer is wrong.
8 isn’t a perfect SQ.
Technically, I’d go for 2

X = 2

Let's solve for x!

√x + √x = √8

Combine like terms:

2√x = √8

Divide both sides by 2:

√x = √8/2
√x = √4
√x = 2

Now, square both sides to get rid of the square root:

x = 2²
x = 4

So, the value of x is 4!

which kain factorise method you use
make i factorise am for u bro
sqrt(x+x)=sqrt.8
that's how yot factorise
if you solve am 4 still be the answer

You answer is wrong..
Because when you squared both sides you'd be left with
2x =8
X=8/2
X=4

Final Answer = 2

COMRADES, we left secondary school over 15 years ago. So count us out

Comrade, I left secondary school about 25 years ago and i didn't need a pen to solve this.

The answer is 4.

To solve this equation, we can first square both sides to get rid of the square roots.

(√x + √x)^2 = (√ 8 )^2

Simplifying the left side, we get:

2x + 2√(x^ 2) = 8

2x + 2x = 8

4x = 8

x = 2

Now we need to check if this value of x works in the original equation.

√x + √x = √8

√2 + √2 = √8

2√2 = √8

Since both sides of the equation are equal when x = 2, we can conclude that this is the correct value of x.

4

Sq both sides.

X + x = 8
2x=8
X=8/2 = 4

If you come Dey talk thrash say answer no Dey, Dey use your head

You can check answer with your block Head.


If x =4
Root 4 + root 4 = ?
2 + 2 = 4
Therefore, is 4 not = to square root of 8?
Yes. Root 8 = 4.
So 4=4.

No Dey waste people data or time.

The square root of 8 is not 4. 8 is not a perfect square. If you substitute the value of 4 back into the equation, it gives us √4 + √4 = 2. So that automatically tells us that 4 is not the correct answer.
If you substitute 2 into the equation, it gives us √2 + √2 = 2√2.
When you convert 2√2 to a single surd, it gives us √8. √8 = √4 x √2 = 2√2. That tells us that √8 is equivalent to 2√2.
In conclusion, 2 is the correct answer.

X=2, because √x+√x=√8

2(√x)=√8

squaring both sides


4x=8

x=2

I like your method, it easiest I see so far, but one thing missing, answer is a, 2

_/2x +_/2x = _/8
2_/2x =_/8. Square both side
2(2x) = 8
4x = 8 divide both sides by 4
x = 8/4
x= 2
