M= sqrt x-2 sqrt x-1 + sqrt x+2 sqrt x-1; b ) N = - Dicamon

Question

M= sqrt x-2 sqrt x-1 + sqrt x+2 sqrt x-1; b ) N = √x 4√x 4 + √x + 4√x 4 ; c ) P = 4√x 4 3 2 d ) M = √x + 5-6√x 4 + √x + 4√x 4 ; g )N= sqrt x-5+2 sqrt x-6 - sqrt

Answer

p= sqrt x+3-4 sqrt x-1 - sqrt x+8-6 sqrt x-1; = sqrt 2^ 2 -2.2 sqrt x-1 +x-1 - sqrt 9-2.3 sqrt x-1 +x-1; = sqrt (2- sqrt x-1 )^ 2 - sqrt 13- sqrt (x-1)^ 2; =12- sqrt x-1 |-13- sqrt
