Do you mean (2 squared) as in E=mv^2

If you do, using BIDMAS E=300 since 10^2 is 100, 100 x 3 = 300

which one?
E=(mv)2 orE=mv2 E= \left(mv\right)^2 \ or E=mv^2

Its the second one, so you write it like ^2.

E=mv2 wherem=3 andv=10E= mv^2 \ where m=3 \ and v=10
E=3×102 E= 3\times 10^2
E=???? E=????
