Square everything.......

then: x+x=8;

2x=8;

therefore 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

Give Tinubu maybe it will help with the economy, if not make una carry una surd waka 😂😂

Rtx + Rtx = Rt8
2Rtx=Rt8
Square both sides (for square to cancel out roots)
4x=8
Divide both sides by 4
X=2.

Just scratching my head for you once again.
B

Bracket root X squared + root X squared. Bracket root 8 squared. Square both sides of the equation. You get root X squared times 2 + root X squared times 2. That gives you 4 root X squared. The other side of the equation gives you root 64 squared.
Cancel out the Square roots on both sides. You get 4X equal to 8. Therefore, X is equal to 2.

U eventually did it.... Great

Just square both side , expand left , root cancels square right ...
You have 4x after expanding left side , right side now has 8
Therefore you 4x=8 , so x=2

[quote][/quote][code][/code]
√x + √x = √8
2√x = √ 4×2
2√x = 2√2
Divide both sides by 2 ( coefficient of √x )
√x = 2√2 / 2
√x = √2
Take the square of both sides
x = 2

I'll really love to see yarimo, helineus, and Jennyclay try and solve it

Re: Mathematicians In The House come over Here by GABRIEL6036: 7:22am On May 25, 2024

To solve the equation √x + √x = √8, we can start by combining the two square roots on the left-hand side:

2√x = √8

Next, we can divide both sides of the equation by 2, which gives us:

√x = √8/2

√x = √(8/2)

√x = √4

Since the square root of 4 is 2, we can write:

√x = 2

Finally, we can square both sides of the equation to solve for x:

x = 2^2

x = 4

Therefore, the value of x is 4.

From mathematician guru, peace unto you all

√(2x) =√8
Square both sides
2x=8
X=4

Lol....Maths guru....u broke basic surd rule...

√8/2 is not equal to √4 ...this is a maths blunder ...u cannot direcrly divide a surd or any root by a whole number

Are u saying √64/2 = √32...instead of 8/2 =4
Or √100/2 = √50 instead 10/2 =5

Wrong
Squaring the left side gives
x^(1/2 *2) + x^(1/2 *2) + x^(1/2 *2) + x^(1/2 *2)
x + x + x + x
4x

and then
4x =8
x = 8/4
x = 2

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

Root 4 plus root 4 is 4 and not root 8 so you're wrong.

The answer is 2 because root 2 plus root 2 is 2root2 which translates to root 8
