Question

HELPPPP !!!!!!!!!!

Answer 1

Below are two expressions. Simplify each and then choose the statement that is true.

Answer 2

Expression #1 ---- > (3x^2)3x^2
Expression #2 -----> (3x^3)^2(x^2)

Answer 3

answer choices

The exponents in Expression #1 are greater than the exponents of Expression #2.

The exponents on Expression #2 are greater than the exponents of Expression #1.

The exponents of Expression #1 are the same as the exponents of Expression #2.

The relationship cannot be determined with the given information.

Answer 4

what do you get when you simplify (3x^2)3x^2

Answer 5

I have no clue

Answer 6

3*3 = ??

Answer 7

9

Answer 8

x^2 times x^2 = ???

Answer 9

4

Answer 10

not just 4

Answer 11

???

Answer 12

x^2 times x^2 is not 4

Answer 13

but 4 is part of it

Answer 14

x^4 ?

Answer 15

good

Answer 16

so (3x^2)3x^2 simplifies to 9x^4

Answer 17

Ok but what statement is true ?

Answer 18

now simplify (3x^3)^2(x^2)

Answer 19

idk how to do that one

Answer 20

(3x^3)^2 is the same as (3x^3)(3x^3)

multiply that out first

Answer 21

9x^6 ?

Answer 22

good

Answer 23

so

(3x^3)^2(x^2)

becomes

(9x^6)(x^2)

Answer 24

multiply that out

Answer 25

18x^8 ?

Answer 26

close, but no

Answer 27

then idk

Answer 28

(9x^6)(x^2)

is the same as

(9x^6)(1x^2)

which becomes what?

Answer 29

idk

Answer 30

what are the coefficients

Answer 31

9 ?

Answer 32

and what else

Answer 33

1 ?

Answer 34

multiply them to get ???

Answer 35

9 ?

Answer 36

9 is the final coefficient

Answer 37

now multiply x^6 and x^2

Answer 38

you did that and got x^8

so the (9x^6)(x^2) simplifies to 9x^8

Answer 39

we started with

Expression #1 ---- > (3x^2)3x^2
Expression #2 -----> (3x^3)^2(x^2)


they both simplify to

Expression #1 ---- > 9x^4
Expression #2 -----> 9x^8

Answer 40

now you just compare the exponents in the simplified expressions

Answer 41

so it would be The exponents on Expression #2 are greater than the exponents of Expression #1 ?

Answer 42

yep you got it

Answer 43

thank you but one more

Answer 44

Expression #1 -----> (3d)^3(d)
Expression #2 -----> (3d^2)^2

Answer 45

same idea really, just with difference expressions

Answer 46

show me what you can do here

Answer 47

So Expression #1 ------> 9d ?

Answer 48

no

Answer 49

(3d)^3 = 3^3 * d^3 = ???

Answer 50

9d^3 ?

Answer 51

3^3 is not 9 though

Answer 52

3^3 = 3 cubed = ??

Answer 53

27 ?

Answer 54

(3d)^3(d)

turns into

(27d^3)(d)

Answer 55

what does (27d^3)(d) become?

Answer 56

27d^3 ?

Answer 57

no

Answer 58

think of (27d^3)(d) as (27d^3)(1d^1)

Answer 59

that mean it would be the same

Answer 60

no not quite

Answer 61

27*1 = 27, yes that stays the same

but something else changes

Answer 62

d^3 * d^1 = ???

Answer 63

d^4 ?

Answer 64

yep

Answer 65

(27d^3)(d) turns into 27d^4

Answer 66

now simplify (3d^2)^2

Answer 67

9d^4 ?

Answer 68

good

Answer 69

Expression #1 -----> (3d)^3(d)
Expression #2 -----> (3d^2)^2

becomes

Expression #1 -----> 27d^4
Expression #2 -----> 9d^4

Answer 70

thank you ! Last question can you also help me simplify (3x^3y^4)^2

Answer 71

how far did you get

Answer 72

Ok so I tried working it out and got 9x^5y^6 ?

Answer 73

good try, but no

Answer 74

when you have (x^3)^2, you multiply the exponents to get x^(3*2) = x^6

Answer 75

use that idea to simplify

Answer 76

so 9x^6y^8 ?

Answer 77

good

Answer 78

so (3x^3y^4)^2 is simplified to 9x^6y^8

Answer 79

yep that is correct

Answer 80

thank you for your help !!!!!!!!!!

Answer 81

you're welcome
