Ben de sondan başlayım :)

C-5

√0,16=√16/100=4/10
√0,25=√25/100=5/10
√1,44=√144/100=12/10

(4/10)+(5/10)-(12/10)=-3/10

c-4

√18=3√2
√200/5=10√2/5=2√2

√√2=∜2

3√2+∜2-2√2=√2+∜2

c-1) 5.√0,64 + 4.√0,25−3.√1+(7/9).

=5. 0,8 + 4. 0,5 −3.√16/9

= 4+2 −3.(4/3)

=6−4=2

c-3

-√27=-3√3
-(-√3)³=3√3
√5²=5

√1=1
√16=4

-3√3+3√3+5

1+4

=

5

5

=1

C-2

a-b=2√5
a+b=2√3

(

a-b

a+b

)²=(

√5

√3

)²=5/3

c-2) ( [(√3+√5)−(√3−√5)] / [(√3+√5)+(√3−√5)] )²

= ( [ √3+√5−√3+√5 ] / [√3+√5 + √3−√5] )²

= (2.√5 / 2.√3 )²

= ( √5 /√3 )²

= 5/3

C-1

5√1-0,36=5√64/100=5.8/10=4


4√1-0,75=4√25/100=4.1/2=2

0,7=7/9 olarak yazılabilir.

1+(7/9)=16/9

3√1+0,777..=3√16/9=3.4/3=3


4+2-4=2 bulunur.
