Question

Which of the following is equivalent to: (4z+12)^4

Answer 1

256(z + 3)^4
4(z + 12)^4
4(z + 3)^4
256(z + 12)^4

Answer 2

I need to know how to do this problem

Answer 3

\[\large{(4z+12)^4 = [(4)(z+3)]^4}\]

Answer 4

right?

Answer 5

yes

Answer 6

but thats not the right answer

Answer 7

256(z + 3)^4 <==== is the answer

Answer 8

wait :
\[\large{4^4 (z+3)^4 = 256 (z+3)^4}\]

Answer 9

4^4 = 256

Answer 10

hence the answer is :
\[\large{256(z+3)^4}\]

Answer 11

got it @Brent0423 ?

Answer 12

could you further simplify it

Answer 13

Yes but there is no need of it

Answer 14

Since the options need no simplification further ..

r u getting my point @Brent0423 ?

Answer 15

yes!

Answer 16

what about (x-5)^3

Answer 17

\[\large{(x-5)^3=(x-5)(x-5)(x-5)}\]

Answer 18

\[\large{(x-5)^2(x-5)=(x-5)^3}\]
right?

Answer 19

ya

Answer 20

what is (x-5)^2 ?

Answer 21

(x-5)(x-5) x^2-10x+25

Answer 22

right good work , now we have:
\[\large{(x-5)^2(x-5)=(x^2-10x+25)(x-5)}\]

Answer 23

\[\large{(x^2-10x+25)(x-5)}\]
\[\large{(x^2)(x)-5x^2-10x(x)-10x(-5)+25x-25(5)}\]

Answer 24

okay i got it!

Answer 25

good you can multiply them and solve..

also :
the formula for (a-b)^3 is:
\[\large{(a-b)^3=(a+b)(a^2-ab+b^2)}\]

Answer 26

X^3-15x^2+75x-125

Answer 27

good gr8 work

Answer 28

Which of the following is equivalent to

\[\frac{ \frac{ t+A }{ 5 } }{ t+A }, t \neq-A\]

Answer 29

how do i figure this one out?

Answer 30

ask this as a new question .. it will be answered there..
