4.55 · [tex] 10^{13} [/tex] - 1.78 · [tex] 10^{12} [/tex]
First let's make [tex] 10^{13} [/tex] the same as [tex] 10^{12} [/tex]. We can do this by multiplying 4.55 x 10, and dividing [tex] 10^{13} [/tex] by 10.
Now we have:
45.5 · [tex] 10^{12} [/tex] - 1.78 · [tex] 10^{12} [/tex]
Now let's subtract 1.78 from 45.5
45.5 - 1.78 = 43.72
Now we have:
43.72 · [tex] 10^{12} [/tex]
But, since the 43.72 has to be in between 1 and 10, we have to divide 43.72 by 100, and multiply [tex] 10^{12} [/tex] by 100.
The answer is:
4.372 · [tex] 10^{13} [/tex]
