Question

2 in scientific notation

Answer 1

Step-by-step explanation: To right a number in scientific notation, first write a decimal point in the number so that there is only 1 digit to the left of the decimal point. Think of 2 as 2.0 and notice that 2.0 already has exactly 1 digit to the left o the decimal point.

This means we would need to move the decimal point 0 places to get back to the original number.

So our answer is 2 × $10^{0}$.

Answer 2

2*10^0 as 10^0 is just 1 and 2*1 is 2
