Question

Which of the following statements is NOT true regarding an expression written in scientific

notation in the form of ax10*?
O The value of a must be greater than or equal to 1 and smaller than 10.
O The value of n must be an integer.
O Doubling n results in a doubling of the value of the expression.
O Doubling a results in a doubling of the value of the expression.

Answer 1

Explanation:

not true is " doubling n results in a doubling of the value of the expression".

e.g.

2.3 × 10² = 230

now I double n :

2.3 × 10⁴ = 23,000

the value of the expression has increased much more than just doubling.
