Question

What is the standard form of 4 x 1 + 1 x 1/100 + 9 x 1/1000 ?

Answer 1

Answer:

4.0109

Step-by-step explanation:

4×1+1×1/100+9×1/1000

Let's ensure that we did not miss any steps

Let's start

4×1=4

1×1/100=0.01

9×1/1000=0.0009

So back to the question

4+0.01+0.0009

4.0109

Depending on the question,they may ask you to leave your in one decimal place or two decimal place

So we will have

4.01 for 2 decimal place

4.0 for 1 decimal place

But since we are not given any condition to leave our answer then the final answer is 4.0109
