Question

observa datele descopera necunoscutele a× a×5= 4×5,y×y×y=1, 3×z×4=5×3×4, 8×u×3=8×6×3

Answer 1

a x a x 5 = 4 x5
a x a x 5 = 20
2 x 2 x 5 = 20

y x y x y = 1
1 x 1 x 1 = 1

3 x z x 4 = 5 x3 x4
3 x z x 4 = 60
3 x 5 x 4 = 60

8 x u x 3 = 8 x 6 x 3
8 x u x 3 = 144
8 x 6 x 3 = 144

Answer 2

a×a×5=4×5 2a×5=20 2a=20:5 2a=4 a=4:2 a=2; y×y×y=1 y=3:3 y=1 3×z×4=5×3×4 3×z×4=60 3×z=60:4 3×z=15 z=15:3 z=5; 8×u×3=8×6×3 8×u×3=144 8×u=144:3 8×u=48 u=48:8 u=6 Sper că te-am ajutat!
