Question

упростить 5√2+2√32-√98=

(45√3+√27)*√3=

(√5-√3) в квадрате =

Answer 1

5V2 + 2V32 - V98 =

=5V2 + 2V16*2 - V49*2 =

=5V2 + 2*4V2 - 7V2 =

=5V2 + 8V2 - 7V2 =

 

 

 

(45V3+V27)*V3 =

=(45V3+V9*3)*V3=

=(45V3+3V3)*V3 =

48V3*V3 = 48*3 = 144

 

 

(V5-V3)^2 = V5^2 - 2V5V3+V3^2 = 5-2V15+3

 

 

по-моему так
