zróbcie mi to zadanko rozpisane jak to wykonać
a) = √16*2 + √36*2 - √25*2= 4√2 + 6√2 - 5√2 = 5√2
b) = √4*3 + √81*3 - √36*3 = 2√3 + 9√3 - 6√3 = 5√3
c) = √16*5 - √25*5 + √100*5 = 4√5 - 5√5 + 10√5= 9√5
d) = √4*7 - √25*7 + √36*7 = 2√7 - 5√7 + 6√7= 3√7
e) = √121*2 - √100*3 + √169*2 - √16*3 = 11√2 - 10√3 + 13√2 - 4√3= 24√2 - 14√3
f) = √400*2 + √16*5 - √100*2 + √100*5 = 20√2 + 4√5 - 10√2 + 10√5 = 10√2 + 14√5
g) = √4*3 + √25*3 + √4*6 + √16*6= 2√3 + 5√3 + 2√6 + 4√6 = 7√3 + 6√6
h) = √196*2 - √25*6 + √289*2 - √81*6 = 14√2 - 5√6 + 17√2 - 9√6 = 31√2 - 14√6
