Estimate 0.037854921 to the nearest hundredth express your answer as a single digit times a power of 10

To solve this problem you must apply the proccedure shown below:

1. Let's round the value to the nearest hundredth. As you can see, the digit 8 is in the thousandths place and is greater than 5, therefore, you must round up to 0.038.

2. Now express the value as a single digit times a power of 10, as following:

x

Therefore, the answer is: x

.

Step-by-step explanation:

We have bee a number 0.037854921. We are asked to estimate the number to the nearest hundredth and and express answer as a single digit times a power of 10.

Round to nearest hundredth (two decimals after decimal):

(Thousandths digit is greater than 5; round up)

Now, we will write 0.04 as a fraction.

Write 100 as a power of 10:

Using exponent rule , we will get:

Therefore, our required number in scientific notation would be .
