You start with 30270000 you write the first number which is 3 then put a decimal and then put the rest of the numbers until the rest of the numbers are zeros..
3.027
Then put a × 10^
3.027 × 10^
And then the original number's digit count minus 1 is the number so 0270000 is 7 digits so the answer is
We need to move the decimal until there is only one digit to the left of the decimal. So we move it 7 places to the left.The 7 becomes out exponent. When we move it to the left, the exponent is positive. If we had moved it to the right, our exponent would have been negative
