[vivid nymph]

consider the property $(a^m)^n = a^{m \cdot n}$

Xer0

consider the property $(a^m)^n = a^{m \cdot n}$

[rugged sparrow]

does he know what degree means?

[shadow bear]

But what do I make of f(x^3)

[shadow bear]

If that would have not been there then the degree would have been 9 I did not understand that part

[main ginkgo]

u can substitute a in place of x^3

[shadow bear]

What is f(x ^3) though

That's the part my brain can't process

[main ginkgo]

just used as a variable

[shadow bear]

Like P(x) ?

[main ginkgo]

it couldve been g(x^3)

exactly

u have to convert the cubic variable into linear

which means substituting a in place of x^3

in both the function and also the eqn

f(a) = 2a^{3} - 3a + 5

[main ginkgo]

no no no

it would be f(a) = 2a^{3} - 3a + 5

u have to suppose that a = x^3

[shadow bear]

How

[main ginkgo]

u have to SUPPOSE

[shadow bear]

BUT WHY

I did not get itt

Oh wait

[main ginkgo]

so that the function f(x^3) which is a cubic function can be converted into linear function which would be f(a)

[shadow bear]

Waittt

Oh got it so basically I'm substituing x^3 by a in the eqn

[main ginkgo]

exactly

[shadow bear]

Ohh cool thnx !!!

[main ginkgo]

much love
