Answer:

It's asking for simplifying expression with the given value.

Explanation:

3x^4 - x + 4; x = 3

3(3)^4 - (3) + 4

3(81) - 3 + 4

243 - 3 + 4

243 + 1

244

Answer:

Explanation:

2) 3x⁴ - 25x³ + 27 = 3(2)⁴ - 25(2)³ + 27 = 3*16 - 25*8 +27 = 48 - 200 + 27

= -125

3) 20s⁴ + 24s³ + 4s = 20(1)⁴ + 24(1)³ + 4(1)

= 20 + 24 + 4 = 48

4) 6m⁴ - 4m +20 = 6(4)⁴ - 4(4) +20

= 6*256 - 16 + 20= 1536 - 16 + 20

=1540

5) - 7p⁴ - p + 9 = -7(-2)⁴ - (-2) +9 = -7*16 + 2 +9 = -112 + 2 + 9 = - 101

6) 6a⁷ - a³ + a = 6(-1)⁷ - (-1)³ + (-1) = 6*(-1) - (-1) - 1 = -6 + 1 - 1 = -6
