2t^2 = 2(2)^2 = 2(4) = 8 when t = 2.

Always remember to take care of the exponents before doing the multiplication. Let me show you why:
If you don't do the exponents first, here's the answer:
2 x 2 = 4 then square that and you get 16
But, if you do the exponents first you get
2^2 = 4 then 2 x 4 = 8
8 is the right answer. Always do the exponents before the multiplication...there is an order of operations.
