Answer:

The answer is -256.

Step-by-step explanation:

You have to substitute the value of b and c into the expression :

${b}^{2} {c}^{1}$

Let b = 8,

Let c = -4,

${8}^{2} \times { - 4}^{1}$

$= 64 \times - 4$

Answer: w+1.3 = 2.7

Reason:

The smaller pieces (w and 1.3) combine to form the larger piece (2.7)

To find w, subtract 1.3 from both sides to get 1.4

1.4+1.3 = 2.7
