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!

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

did you get the answer yet?

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
