Question

how do you solve in scientific notation such as the 25.63 in scientific notation

Answer 1

Move the point to the left till there's only 1 number before the point.
You begin with \(\large 25.63\times 10^0\)
With every movement of the point to the left, you add 1 to the exponent after 10.
so 1 to the left and it'll become \(\large 2.563\times 10^1\)
Now you usually only use 2 significant figures AFTER the point so it will be \(\large 2.56\times 10^1\)
