Answer 1

Answer:

1) 5417.412

2) 401.13

Step-by-step explanation:

1) $5 \times 10^3 + 4 \times 10^2 + 1 \times 10^1 + 7 \times 10^0 + 4 \times \frac{1}{10^1} + 1 \times \frac{1}{10^2} + 2 \times \frac{1}{10^3}$

$5 \times 10^3 = 5000 \\ 4 \times 10^2 = 400 \\ 1 \times 10^1 = 10 \\ 7 \times 10^0 = 7 \times 1 = 7 \\ 4 \times \frac{1}{10^1} = 0.4 \\ 1 \times \frac{1}{10^2} = 0.01 \\ 2 \times \frac{1}{10^3} = 0.02$

Combining we have: $5000 + 400 + 10 + 7 + 0.4 + 0.01 + 0.002 =$ 5417.412.

2) $4 \times 10^2 + 1 \times 1\frac{1}{10^1} + 3 \times \frac{1}{10^2}$

$4 \times 10^2 = 400 \\ 1 \times 1\frac{1}{10^1} = 1 \times \frac{11}{10} = 1 \times 1.1 = 1.1 \\ 3 \times \frac{1}{10^2} = 0.03$

Combining we have: 400 + 1.1 + 0.03 = 401.13.

Hence, we have the answers.

Answer 2

Answer:

A) The sum of given digits is 5417.412

B ) The sum of given digits is 401.103  

Step-by-step explanation:

Given sum of numbers as :

A ) 5 × 10³ + 4 × 10² + 1 × $10^{1}$ + 7 × $10^{0}$ + 4 × $\frac{1} {10^{1}}$ + 1 × $\frac{1}{10^{2}}$ + 2 × $\frac{1}{10^{3}}$

Or , 5000 + 400 + 10 + 7 × 1 + 0.4 + 0.01 + 0.002

or, ( 5400 + 10 + 7 ) + ( 0.4 + 0.01 + 0.002 )

Or, 5417 + 0.412

Or, 5417.412

Hence The sum of given digits is 5417.412

B ) 4 × 10² + 1 × ( 1 $\frac{1} {10^{1}}$ ) + 3 × $\frac{1}{10^{3}}$

Or, 400 + 1 × ($\frac{10+1}{10}$ ) + 0.003

Or, 400 + $\frac{11}{10}$ + 0.003

Or, 400 + 1.1 + 0.003

Or, 401.103

Hence The sum of given digits is 401.103
