Which statement shows (7×105)+(5×103)+(4×101)+(6×100)

Question

?
A.
7,546

B.
75,046

C.
705,046

D.
705,406

Answer 1

To evaluate the expression \((7 \times 10^5) + (5 \times 10^3) + (4 \times 10^1) + (6 \times 10^0)\), we first calculate each term:

1. \(7 \times 10^5 = 700,000\)
2. \(5 \times 10^3 = 5,000\)
3. \(4 \times 10^1 = 40\)
4. \(6 \times 10^0 = 6\)

Now, we can add these values together:

\[ 700,000 + 5,000 + 40 + 6 \]

Calculating this step-by-step:

\[ 700,000 + 5,000 = 705,000 \]

\[ 705,000 + 40 = 705,040 \]

\[ 705,040 + 6 = 705,046 \]

Thus, the value of the expression is \(705,046\).

The correct answer is C. 705,046.
