Answer 7

well what you need to rewrite the numbers correctly in scientific notation

\[0.176 \times 10^{18} = 1.76 \times 10^{17}\]

scientific notation is a number between 1 and 10 that is then multiplied by a power of 10

looking at star D \[125.5 \times 10^{15} = 1.255 \times 10^{17}\]

since to powers of 10 are the same, you can subtract,

Any scientific calculator should easily do this problem.

Answer 8

So, I subtract the 2 decimals?

Answer 9

no you are subtracting

\[1.76 \times 10^{17} - 1.255 \times 10^{17} = ( 1.76 - 1.255)\times10^{17} \]

then you will probably need to adjust the power of 10

Answer 10
