1. ## math

simplify,and verify the result for the given values (-3x^2 )(4xy^2(-2/3x^2) for x=3/4 and y=3

2. Simplify:-
(-3x^2 )(4xy^2(-2/3x^2)
(9x^2)(16x^2y^2)(4/9x^2)
(144x^4y^2)(4/9x^2)
576x^4y^2/9x^2
64x^2y^2
verify the result for the given values (-3x^2 )(4xy^2(-2/3x^2) for x=3/4 and y=3:-
u already know that all of this (-3x^2 )(4xy^2(-2/3x^2) is this 64x^2y^2
so now all u have to do is replace
64(3/4)^2(3)^2
64(0.5625)(9)

Your bracketing is faulty; should "probably" be:

(-3x^2 ) (4xy^2) ((-2/3)x^2)

That's if you mean multiplying those 3 terms together.
Something like your -2/3x^2 is VERY unclear;
like, is it -2 divided by 3 times x^2, or -2 divided by (3x^2), or (-2/3) times x^2 ?

4. i know but the thing is, u cant put it to the power of something in this reply, so that is why its confusing
and yes i do mean that we should multiply them togather...
