Question

57. If a = (3+ V2) and b = (V3-v2), find the value of (a + 1)- + (b + 1)-1
(a) 4
(b) 3
(c) 1
(d) 0​

Answer 1

Answer:

d)0

Step-by-step explanation:

a=3+v2 b=v3-v2

a+1=3+v2+1 b+1=v3-v2

=4+v2 =v3-(-4)+1

v2= -4 v3=-5

a=3+(-4) b= -5-(-4)

a= -1 b= -1

(a+1)-1+(b+1)-1=(-1+1)-1+(-1+1)-1

=(0)-1+(0)-1

=0
