2]a^4+(root under 2b)^4
3]x^4+5x^2+9
4]p^2-10xp+16x^2-q^2+6xq
solve it

1) a^4 + 16b^4

2) x^4 + 5x^2 + 9

3) p^2 − 10px − q^2 + 6qx + 16x^2

Step-by-step explanation:

1) a^4 + (2b)^4

= a^4 + 16b^4

2) x^4 + 5x^2 + 9

There are no like terms.

= x^4 + 5x^2 + 9

3) p2 − 10xp + 16x2 − q2 + 6xq

= p^2 − 10px − q^2 + 6qx + 16x^2
