Answer:
Step-by-step explanation: To write 49 in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
So here we have 4.2. Next, count the number of places that we would need to move the decimal point in 4.2 to get back to the original number which is 42.
Since we would need to move the decimal point 1 place to the right to get back to the original number, we would need to multiply 4.2 by 10 to the 1st power. The exponent is positive because we need to move the decimal point to the right.
Therefore, 42 can be written in scientific notation as 4.2 ×
