(3) (y squared) [2 (y cubed)]^4
Here is a hint:
a^2 = a*a
a^3 = a*a*a
a^4 = a*a*a*a
... and so forth.
So, what is (2 times y^3)?
Answer: (2y^3) = 2*y*y*y
What do you get if you write out (2y^3)^4?
Well, it would be (2*y*y*y) times itself four times.
Write it all out, and see what you get.

3y²(2y³)^4 = 3y²(2^4)(y^(3*4))
= 3y²(16)(y^12) = 3*16*y^(2 + 12) = 48y^14

3y^2 (16y^12) <----- raise 2 to the exponent 4 and multiply exponents
= 48 y^14 <----- multiply coefficients and add the exponents

3y^2(16y^12) = 48y^14

3y^2(2y^3)^4=3y^2[2^4(y^12)]
=3y^2(16y^12)
=48y^14
