c) (-\(\dfrac{1}{3}\))\(^3\)
d) (-1\(\dfrac{5}{7}\))\(^2\)
e) (-0,6)\(^4\)
f) (-\(\dfrac{3}{25}\))\(^0\)

Giúp em với ạ, plss.THANK YOU SO MUCH<33

 

Answer 1

\(a,\left(\left(-0,5\right)^2\right)^3=\left(-0,5\right)^6=0,015625\)

\(b,\left(-\dfrac{2}{3}\right)^4=\dfrac{16}{81}\)

\(c,\left(-\dfrac{1}{3}\right)^3=\dfrac{-1}{27}\)

\(\left(-1\dfrac{5}{7}\right)^2=\left(-\dfrac{12}{7}\right)^2=\dfrac{144}{49}\)

\(e,\left(-0,6\right)^4=0,1296\)

\(f,\left(-\dfrac{3}{25}\right)^0=1\)

Answer 2

a) [(-0,5)²]³ = [(-1/2)²]³ = (1/4)³ = 1/64

b) (-2/3)⁴ = 16/81

c) (-1/3)³ = -1/27

d) (-1 5/7)² = (-12/7)² = 144/49

e) (-0,6)⁴ = (-3/5)⁴ = 81/625

f) (-3/25)⁰ = 1
