Answer 1

Ответ:

y=5*4а*3+4*4а

у=60а+4а

у=64а

у=64*4

ответ 256

Answer 2

To find the value of the function y(x) = 5x^3 + 4x when x = 4a, simply replace x with 4a in the expression for y(x) and evaluate the result.

y(4a) = 5(4a)^3 + 4(4a)

Now, let's simplify this expression:

y(4a) = 5(64a^3) + 16a

y(4a) = 320a^3 + 16a

So, the value of the function y(x) when x = 4a is 320a^3 + 16a.
