Answer 1

$frac{3}{5}a^2b^2=frac{3}{5}2^2(frac{3}{5}) ^2=frac{108}{125}$

$0,4ab*8b^2=2,4ab^3=2,4*0,5^2*3^3=16,2$

$0,5ab^3*16a^2b=8a^3b^4=8*(-0,5)^3*(-2)^4=-16$

$frac{5}{18}a^3b^4*frac{18}{5}a^4b^4=a^7b^8=(-frac{1}{5})^7*(-5)^8=-5$

Answer 2

1) 0.4*8=3.2 2) a*b³=...(0.5)*(27)

Answer 4

1) =3*а²b²/5= 3*2²*2²/(5*5²)= 108/125
2) =3.2*a*b³=3.2*(-0.5)*3³=-43.2
3) =8*a³*b⁴=8*(-0.5)³*(-2)⁴=-8*0.125*16= -16
4) =1*a^7*b^8=(-1/5)^7*(-5)^8=-5
