the next number is an exponenet

Answer 6

(3x-7y^4)^2
(3x-7y^4)(3x-7y^4)
3x(3x-7y^4)+(-7y^4)(3x-7y^4)
3x(3x-7y^4)-7y^4(3x-7y^4)

can you do the last step?

Answer 7

yes thx so much

Answer 8

np, tell me your final result, to make sure it's right :)

Answer 9

9x-7y^4+49y^16

Answer 10

9x^2

Answer 11

No.

Answer 12

oh ok can u help me

Answer 13

3x(3x-7y^4) = 9x^2 - 21xy^4
-7y^4(3x-7y^4)= -21xy^4+49y^8

so
9x^2 - 21xy^4-21xy^4+49y^8
...
9x^2 - 42xy^4+49y^8


alternatively, you could have used, \[(a-b)^2=a^2-2ab+b^2\]

Answer 14

3x is your a
7y^4 is your b

Answer 15

thx so much I understand it now
