Question

Va rog mult de tot!!!!!!
22 si 24....Va roggggggggg!

Answer 1

Numai 22-ul am avut timp

22.a.) Radical 12la2+9la2=

Radical 3la2*4la2+9la2=

Radical 9*(4la2+9)=

Radical 9*(16+9)=

Radical9*25=3*5=15

22b.)

Radical 15la2-9la2=

Radical3la2*5la2-3la2*3la2+

Radical 3la2(25-9)+

Radical 3la2*16=

3*4=12

22.c.)

Radical 15la2+20la2=

Radical 3la2*5la2+4la2*5la2=

Radical 5la2*(3la2+4la2)=

Radical5la2*(9+16)=

Radical 5la2*25

5*5=25

22.d)

Radical 3la2*10la2-3la2*8la2=

R 3la2*(10la2-8la2)=

R 3la2*(100-64)=

R 3la2*36

3*6=18

22.e.)

R 9*25+64=

R289=17

22.f

R 3la4*(13la2-5la2)=

R 3la4*(169-25)=

R 3la4*144=

3la2*12=9*12=108

22.g.

R 7la2*(2la6+4*9)=

R 7la2*(64+36)=

R 7la2*100=

7*10=70

De punctul 24 nu mai am timp, sorry
