Cuanto me da como resultado
Likurg_2 [28]

Step-by-step explanation:

1) (-4)^2{\cdot}(-4)

We know that, a^x{\cdot}a^y=a^{x+y}

(-4)^2{\cdot}(-4)=(-4)^{2+1}\\\\=(-4)^3\\\\=64

2) (-2)^5{\cdot} (-2)^3

Again using above property,

(-2)^5{\cdot} (-2)^3=(-2)^8\\\\=256

3) 5^{-3}

We know that,

a^{-x}=\dfrac{1}{a^x}

So,

5^{-3}=\dfrac{1}{5^3}\\\\=\dfrac{1}{125}

4) 2.5^2=2.5\times 2.5\\\\=6.25

Hence, this is the required solution.
