Need help dtermining if following are true... Is P->(QVR) equivalent to Pn~Q -> R (Know would convert P->(QvR) to ~Pv(QvR) can't you convert that to (~PvQ)vR then finally Pn~Q->R to prove it true?) If x
Need help dtermining if following are true...
Is P->(QVR) equivalent to Pn~Q -> R
(Know would convert P->(QvR) to ~Pv(QvR) can't you convert that to (~PvQ)vR then finally Pn~Q->R to prove it true?)
If x<y then x^4<y^4 (would this be false as if x is -3 and y -2 this causes the initial statement to be wrong by the conclusion?)
x^4<y^4 then x<y (Would this be true as it would cover the negative cases cause if x were -3 then y^4 would have to be greater than -3^4)
If 22|a and 6|a then 132|a (How would you explain this to be true I know 132 would be least common multiple)
The last digit of 6^400 is 6? (How would you prove problems like this or find out if true where have a crazy large number and need to find the last or 2nd last digit?)
