If vmt ≠0, is (v^2)(m^3)(t^-4) > 0?
(1) m > v^2
(2) m > t^-4
(1) m > v^2
(2) m > t^-4
Info from the question
vmt ≠0 i.e. v, m or t are not 0.
Question is asking is (v^2)(m^3)(t^-4) > 0 i.e. is m positive (note v or t can be positive or negative but end result will always be positive considering even a negative value raised to the power of a positive value yields a positive result i.e. -2 ^ 2 = + 4)
Statement 1
m > v^2
Result v^2 will always be a positive value.
i.e. m is positive so the whole equation is positive.
The statement is sufficient.
Statement 2
m > t^-4
m > 1 / t^4
Result of 1 / t^4 will always be a positive value.
i.e. m is positive so the whole equation is positive.
The statement is sufficient.
In my opinion the Answer is D
