Answer:
<h2><em>1×10⁻⁴ and 9.8×10⁵</em></h2>Step-by-step explanation:
The standard form of writing a scientific notation is expressed as where a, b and n are integers. Note that a, b and n cannot be a fraction. When writing in scientific notation, the value of 'a' must not be equal to zero and it must not be a 'two digits values' but just 'a digit value'.
<em>Based on the above conclusion, the following numbers are correctly written in scientific notation.</em>
<em>1×10⁻⁴ and 9.8×10⁵</em>
- The expression 10.8×10 −3 is not correctly written because the value of a on comparison is a two digits number i.e 10.
- Also, 0.54×10^6 is not correctly written because a is zero on comparison
- 7.6×10 2.5 is not correctly written because the power is a decimal number i.e 2.5. We must only have an integer as the degree.
