Answer :

Let's solve each expression step-by-step.

First, let's work on the expression [tex]\((-2)^3 + 10^0 + 8^1 + 0^3 + 6^3\)[/tex]:

1. Calculate [tex]\((-2)^3\)[/tex]:
[tex]\[ (-2)^3 = -2 \times -2 \times -2 = -8 \][/tex]

2. Calculate [tex]\(10^0\)[/tex]:
[tex]\[ 10^0 = 1 \][/tex]

3. Calculate [tex]\(8^1\)[/tex]:
[tex]\[ 8^1 = 8 \][/tex]

4. Calculate [tex]\(0^3\)[/tex]:
[tex]\[ 0^3 = 0 \][/tex]

5. Calculate [tex]\(6^3\)[/tex]:
[tex]\[ 6^3 = 6 \times 6 \times 6 = 216 \][/tex]

Next, add all the terms together:
[tex]\[ (-8) + 1 + 8 + 0 + 216 = 217 \][/tex]

So, the value of the first expression is:
[tex]\[ (-2)^3 + 10^0 + 8^1 + 0^3 + 6^3 = 217 \][/tex]

Now, let's work on the expression [tex]\(3^{-2} + 6^{-1}\)[/tex]:

1. Calculate [tex]\(3^{-2}\)[/tex]:
[tex]\[ 3^{-2} = \frac{1}{3^2} = \frac{1}{9} \approx 0.1111 \][/tex]

2. Calculate [tex]\(6^{-1}\)[/tex]:
[tex]\[ 6^{-1} = \frac{1}{6} \approx 0.1667 \][/tex]

Next, add these terms together:
[tex]\[ 0.1111 + 0.1667 = 0.2778 \][/tex]

So, the value of the second expression is:
[tex]\[ 3^{-2} + 6^{-1} \approx 0.2778 \][/tex]

Therefore, our final results are:
[tex]\[ (-2)^3 + 10^0 + 8^1 + 0^3 + 6^3 = 217 \][/tex]
[tex]\[ 3^{-2} + 6^{-1} \approx 0.2778 \][/tex]
