Question

Efectuati:
2$\frac{1}{2}$·$\sqrt{0.0144}$+$(-1)^{11}$·$\sqrt{0.16}$+0.1(6)·$\sqrt{0.36}$
Va rog mult sa ma ajutati!!!

Answer 1

√0,0144=√(144/10000)=12/100=3/25
(-1)^11=(-1)
√0,16=√(16/100)=4/10=2/5
0,1(6)=(16-1)/90=15/90=1/6
√0,36=√(36/100)=6/10=3/5
5/2×3/25+(-1)×2/5+1/6×3/5=3/10-2/5+3/30 amplificam 3/10 cu 3 si pe 2/5 cu 6
9/30-12/30+3/30=(-3/30)+3/30=0
