Answer:

Option C

Step-by-step explanation:

Given : An expression written in scientific notation in the form of \(a\times 10^n\)

Let \(x=a\times 10^n\)

To find : Which statement is not true for the expression.

Solution :\(10^n\) is a power, with a base of 10 and an exponent of "b".

''n" is associate whole number like the quantity of places the decimal "moves".

→ When the exponent "n" is positive (and not zero), the number "x" is greater than one.

→ The larger the exponent "n", the larger the number "x".

→ When the exponent "n" is negative, the number "x" is between zero and one.

→ The smaller the exponent "n", the nearer the quantity "x" is to zero.

From the above statements we say that Option C - Doubling n results in a doubling of the value of the expression is incorrect or not true
