@fleet garden

#

I dont know how to solve this

#

answer is 4

#

is the question framed correctly or there is amistake

#

@fleet garden

fleet garden
#

so x+y+z=6 agreed?

merry quiver
#

That is not

#

In question

#

Question says and f(6)

#

Does not say f(x+y+z) = 6

fleet garden
#

it says f(x+y+z)=f(x)f(y)f(z)

merry quiver
#

Yes

fleet garden
merry quiver
fleet garden
#

I wrote x+y+z = 6

merry quiver
#

What logic

fleet garden
#

which we can conclude from f(6) = 64

#

f(6) = 64
f(x+y+z)=f(x)f(y)f(z)

merry quiver
fleet garden
#

if I say f(x) is something

merry quiver
#

Okay

fleet garden
#

and then I say f(4) is something else

#

we substituted x for 4

#

in that same function

merry quiver
#

U just did 6 = 64

#

F(6)

fleet garden
#

if I say f(x) = x+1
then f(1) is ?

merry quiver
#

And hit and trial

#

Am I right

fleet garden
#

what

#

we are given that f(x+y+z) = f(x)f(y)f(z)

merry quiver
#

what does f(x+y+z) mean it means f(x) multiplied to f(y) to f(z)

fleet garden
#

and we are given that f(6) = 64

#

so we can assume x+y+z = 6 and f(x)f(y)f(z) = 64

#

I'm just substituting

merry quiver
#

Explain to me like a 5

#

Year old

#

You are making it too complex

fleet garden
#

if I say f(x) = x+1

#

what is f(1)

merry quiver
#

2

fleet garden
#

how did you do that

merry quiver
#

X as 1

#

Cmon

fleet garden
#

so f(1) = 1+1

merry quiver
#

Yes

fleet garden
#

if I say f(1) = 2
and I say f(x) = x+1

#

can I take 1 from the first equation from the f(1) and say x=1?

#

and can I take x+1 and say it's equal to 2?

merry quiver
#

Yes

fleet garden
#

that's the same thing we're doing here:
f(6) = 64
f(x+y+z) = f(x)f(y)f(z)

#

I can say what's in the parentheses is equal

#

x+y+z = 6

#

and if that's the case, then f(x)f(y)f(z) = 64

merry quiver
#

What does f(x)f(y)f(z) mean does it mean multiplied

fleet garden
#

yes

#

same function multiplied for different values x,y,z

merry quiver
#

okay?

fleet garden
#

we know the problem is asking for f(2)

merry quiver
#

So

#

f(2) =

fleet garden
#

so it would be convenient to have f(2) so we can solve for it

#

split up the 6 into a sum of 2s

merry quiver
#

2+2+2 = 6

fleet garden
#

correct

#

f(2+2+2) = 64

#

or f(x+y+z) = f(x)f(y)f(z)

#

so we can write f(2+2+2) = f(2)f(2)f(2)

#

agreed?

merry quiver
#

Yes

fleet garden
#

we know f(2+2+2) is the same as f(6)

#

and we know f(6) is 64

#

so we can write f(2+2+2) = f(6) = 64

#

and we can write f(2)f(2)f(2) = 64

#

because f(2)f(2)f(2) is just f(2+2+2) which is f(6)

#

following?

merry quiver
#

Yes

#

I am

#

@fleet garden

fleet garden
#

good

#

so when something is multiplied with itself 3 times we can write it as something to the power of 3

#

$aaa = a^3$

#

okay?

fleet garden
#

that's what we're doing here

merry quiver
#

2^3 is not = 64 2^6

#

Is

fleet garden
#

$f(2)f(2)f(2) = (f(2))^3$

but we're not calculating $2^3$

#

How u know y value and z value and x value it could have been 2 +3+1

fleet garden
#

we're calculating (f(2))^3

#

you won't get far with 2+3+1

#

because you don't know f(3) and f(1)

#

and you don't need them

merry quiver
#

Ok

#

Neither I know f(2)

fleet garden
#

you need f(2) which is why you're using it. it's convenient

#

yeah but you need to find it

#

you don't need to find f(1)

#

or f(3)

merry quiver
#

Ok

#

f(x) = x^2

fleet garden
#

we're using f(2) because it's actually convenient to find the solution that way

merry quiver
#

And here f(x) = turns out to be 2^3.2

fleet garden
#

$(f(2))^3 = 64$

$f(2)f(2)f(2) = 64$ if that's easier

what number multiplied by itself 3 times gives 64

Result:

8
fleet garden
#

no

merry quiver
#

Then what

fleet garden
#

figure it out

#

f(2) is not 2, it's just a function's value for x=2

merry quiver
#

I don't know

#

@fleet garden Don't close this

#

I'm sleeping

#

Tired af

#

I'll come back and sort this

fleet garden
#

I wont, look at it tomorrow

merry quiver
#

i understood

Sleep helped 🙂
