Calculate: (7.15 x 109) − (4.56 x 108)

Question

Group of answer choices

2.59 x 101

6.694 x 108

6.694 x 109

Answer 1

To solve the expression \( (7.15 \times 10^9) - (4.56 \times 10^8) \), we first need to express both terms with the same exponent.

We can rewrite \( 4.56 \times 10^8 \) in terms of \( 10^9 \):

\[ 4.56 \times 10^8 = 0.456 \times 10^9 \]

Now we can rewrite the expression as:

\[ (7.15 \times 10^9) - (0.456 \times 10^9) = (7.15 - 0.456) \times 10^9 \]

Calculating \( 7.15 - 0.456 \):

\[ 7.15 - 0.456 = 6.694 \]

Now substituting back, we have:

\[ 6.694 \times 10^9 \]

So, the final answer is \( 6.694 \times 10^9 \).

Since this choice is not listed, let's double-check if the choices are consistent. The answer you provided should be \( 6.694 \times 10^9 \).

Since \( 6.694 \times 10^9 \) is not among the listed options, please ensure there isn’t a typo or a misunderstanding in the problem or your options.
