More Algebra questions

[Zap Brannigan]

Now I need to combine like terms.....

square root of 45 + square root of 80 - the cubed root of 20

 

[Zap Brannigan]

Anyone have any tips?

Am I the only one that thinks they should spend more time teaching 'practical math' instead of all this abstract stuff?

/me is 31 years old and has not thought about algebra since 1992. /me wonders how he exists without it.

Well right now this is practical math since it's kind of fun and plus algebra is all aout simpl;ifying problems, which is kind of key for more complex equations, some of which are practical.

In other news I am making progress on this problem,

So far I have,

Square root of 9(5) + square root of 16(5) - cubed root 4(5)

Oh I see where this one is going, time to solve this byatch!

 

[Zap Brannigan]

and it's not cubed root is a 3 times square root, woops lol.

Actually practical math would be finance, banking, amortization, taxes, percents, etc. I can assure you unless you are going into a specific field you will have no need for any of this.

I'm thinking about majoring in CIS. Probably won't need Algebra but it's still kind of fun.

I got square root5 for my last answer.

 

[Zap Brannigan]

Anyone still here?

 

[Zap Brannigan]

I might need some help with the next one.

Ok on this one I needs to combine like terms where possible.

sqyare root 44 -3 square root 63x + 4 square root 28x

To become a Moon Warrior I must solve this, Simplify the cubed root of 24m

(24m)^(1/3)
=(3m*2^3)^(1/3)
= (2^3)^(1/3)*(3m)^(1/3)
=2*(3m)^(1/3)

This is practical. I use this stuff everyday in EE.
