Question translated into English:
Write in standard form: 0.898×10⁵
Answer:
Standard form is given by the form A×10ⁿ
Where A is a value in unit and 'n' is for all integers
0.898 is not in unit so we need to rewrite this as 8.98×10⁻¹
Write them together with the 10⁵, we have
8.98×10⁻¹×10⁵ = 8.98×10⁻¹⁺⁵ = 8.98×10⁴
