Answer 1

Step-by-step explanation:

$\bold{A. \: 1). \: 8 \times 1 {0}^{ - 5}m \: }$

$\bold{2). \: \: \: 3.1 \times {0}^{7} \degree \: F}$

$\bold{3). \: 8.17 \times 1 {0}^{6} \: {m}^{2} }$

$\bold{ \: B.1). 1900000000000000000000000000 \: kg}$

$\bold{5). \: 60400000 \: m}$

The questions are easy.

1) If the question is asking to transform the scientific notation into decimal then, count the number of 0's ( For example, 3.23*10^2 km . Here the number of zeroes are 2, therefore, the decimal form will be 323 km ) and place them.
