ответ: 1.   5¹⁰ +5⁸ -5⁹ =5⁸(5² +1 -5) = 5⁸*21 =5⁷*5*21 =5⁷*105       || делится на 105||  .

2.  √(1 24/25 ) -√(0,09)*√81 +√(3² +4²)*√(0,0625)   =√(49/25) -√(9/100) *√9² +√5² *√(0,25)² =7/5 -9/10*9 +5*0,25 =

1,4 -8,1+1,25   = -5,45.

3. a =13q₁ +8 ; b=13q₂ +10 .

a*b = (13q₁ +8)(13*q₂ +10) = 13²  q₁q₂   +13*10q₁ +  13*8q₂+ 80 =.

13²  q₁q₂   +13*10q₁ +  13*8q₂+ 13*6 +  2 =13(13 q₁q₂   +10q₁ + 8q₂+ 6) +2  .   || r =2||.

4.√((7-4√3)/(5-2√6)) -√((6-4√2)/(5+2√6)) -4√2 =√((2²-2*2√3 +(√3)²)/(3-2√3*√2 +2)) -√((4-2*2*√2 +2)/(3+2√3*√2 +2) )  -  4√2 =  √((2-√3)²)/(√3-√2)²  ) -√((2-√2)²/(√3+√2)²) -  4√2 = (2-√3)/(√3-√2)  -(2-√2)/(√3+√2) -  4√2 = (2-√3)(√3+√2)  -(2-√2)(√3-√2) -  4√2  =

2√3+2√2 -3 -√3*√2 -2√3  +2√2 +√3*√2 -2 -  4√2   = -  5.  

5. (x² +x√2)/(x² +2) *(  x/(x-√2) -√(2)  / (x+√2) ) =

(x² +x√2)/(x² +2)   *(x(x+√2) -√(2) *  (x-√2)  )  / (x+√2)  (x-√2)  )= 

(x² +x√2)/(x² +2)   *(x²+x√2 -x√2  +2  )  / (x² -2) )=

  (x² +x√2)/(x² +2)   *(x²  +2  )  / (x² -2) )   =   x(x+√2)  / (x +√2)(x -√2)  =x  /(x -√2) .

6. (  √(19 +8√3) +√(7-4√3) ) *x√y /(√x²y³ +√x³y²) =

(  √(4+√3)² +√(2  -√3)² ) *x√y /xy(√y +√x)  =( 4+√3  +2  -√3  ) *1 /  √y(√y +√x  )  =

6/√y  (√y +√x  )=   || x =121 , y =16 || = 6/(√16(√16 +√121  )) =6/(4(4+11)) =

=6/(4*15) =6/60 =  0,1.
