Julian fully simplifies this polynomial and then writes it in standard form. 4x2y2 – 2y4 – 8xy3 + 9x3y + 6y4 – 2xy3 – 3x4 + x2y2 if julian wrote the last term as –3x4, which must be the first term of his polynomial in standard form? 4y4 6y4 –2xy3 –10xy3

  4x²y² - 2y⁴ - 8xy³ + 9x³y + 6y⁴ - 2xy³ - 3x⁴ + x²y²

= 5x²y² +4y⁴ - 10xy³ + 9x³y - 3x⁴      combined like terms

= -3x⁴ + 9x³y  + 5x²y²  - 10xy³ + 4y⁴     descending exponent order based on "x"

If Julian wrote his list in descending order based on "y", then the order would be reversed.

 4y⁴

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

sorry, i don't know i just need points, i'm new here. chao
