Please what is the answer?

740.8×10^-2

Step-by-step explanation:

To solve this question,we need to follow the step by step procedure to prevent mistakes

Firstly I will start with 7×1=7

Followed by 4×1/10

One has to be careful with this,

4×1/10=4/10

We could solve further by convert to decimal,which will give 0.4

Next one is the 8×1/1000

Just like the second one we will follow the same step that is,

8×1/1000=0.008

Back to the question,(7×1)+(4×1/10)+(8×1/1000)

Input the values we've calculated earlier,

7+0.4+0.008

=7.408

To standard form,the decimal point will be shifted to the right
