Question

find the value of above :

Answer 1

hope my answer helps you.

Answer 2

Answer:

2 is the answer.

Step-by-step explanation:

(I Part away with the expressions individually for ur better understanding.)

(1/2)*-1 which is equals to 2 Because negative signs brings about changes in numerator and denominator if the number given in a fractional form. And 1 means 1*2 . So, the answer is 2.

(4)*-1 which is equals to 1/4 Because Negative sign brings about changes of the number, When the number is whole number, then we would put the the whole no (as given here 4) in the denominator and in the numerator part there  Comes 1. So, The answe would be 1/4 and 1*4 is 4.

Now, arranging The Expression.

{ (1/2)-1 * (4)*-1 }*-1

= { 2 *1/4 }*-1

= { 1/2 }*-1  (we got the result by multiplying 1/2*4)

=2 is the answer. (As Negative sign brings about changes in the numerator and denominator and 1*2 is 2 )
