9x10x10-5.54x10 to the 4

Answer 1

To calculate \( 9 \times 10^{10} - 5.54 \times 10^{4} \), we can first express both terms using the same power of ten for easier subtraction.

The first term \( 9 \times 10^{10} \) is already in the correct format. The second term \( 5.54 \times 10^{4} \) can be expressed as \( 0.0000554 \times 10^{10} \) when adjusted to the same power of 10.

Now we can rewrite the problem:

\[ 9 \times 10^{10} - 0.0000554 \times 10^{10} = (9 - 0.0000554) \times 10^{10} \]

Calculating the subtraction:

\[ 9 - 0.0000554 = 8.9999446 \]

Now, we can express the final result:

\[ 8.9999446 \times 10^{10} \]

So,

\[ 9 \times 10^{10} - 5.54 \times 10^{4} = 8.9999446 \times 10^{10} \]

If further simplification is needed, you can round it based on the required precision.
