This is about expression in standard form.
Given expression in standard form is 8.059.
8 × 1 + 5 × (1/100) + 9 × (1/1000)
Let us arrange in brackets first before multiplying;
(8 × 1) + (5 × (1/100)) + (9 × (1/1000))
Let's take each of them individually before adding up;
8 × 1 = 8
5 × 1/100 = 0.05
9 × 1/1000 = 0.009
>> 8 + 0.05 + 0.009
>> 8.059
Thus,the given expression in standard form is 8.059.
