1) Demuestre Si la proposición ¬ ( p Ʌ ¬ q Ʌ ¬ r) es falsa, entonces la proposición

p → ( q Ʌ r ) es:

a) Verdadera b) Falsa

2) Identifique cuál de las siguientes formas proposicionales NO es tautológica.

a) (p v q ) → (¬p →q)

b) [ (p → r ) Ʌ ( q → r ) ] → [ ( p v q ) → r ]

c) [ ( p v q ) Ʌ ¬p ] → q

d) [ ( ¬q → ¬p ) ] → ¬q

e) [(p → q ) Ʌ ( q → r )] → (p → r )

AYUDAAA, HELP MI PLS.

Muchas gracias de antemano!

you have orange juice on wednesday. (idk why this is the answer)

step-by-step explanation:

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.

you didn't give an question you just gave us a statement
