Now write the in standard form =
Please what is the answer?

Answer:
7 ones, 4 tenths,8 thousandths
Step-by-step explanation:
(7×1)+(4×1/10)+(8×1/1000)
=7+4/10+8/1000
=7.408
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
740.8×10^-2
