Doprowadź do postaci a √2 :
a) √32 - 3√2
b) √18 + √8
c) √200-√50
d) √18+√72+√98
e)√800 +√242-162
a) V32-3V2 = 4V2-3V2 = V2
b) V18+V8 = 3V2+2V2 = 5V2
c) V200-V50 = 10V2-5V2 = 5V2
d) V18+V72+V98 = 3V2+6V2+7V2 = 16V2
e) V800+V242-V162 = 20V2+11V2-9V2 = 22V2
√16x2-3√2=4√2-3√2=√2
√9x2+√4x2=3√2+2√2=5√2
√100x2-√25x2=10√2-5√2=5√2
√9x2+√36x2+√49x2=3√2+6√2+7√2=16√2
√400x2+√121x2-√81x2=20√2+11√2-9√2=22√2
