Answer 2

Answer:

The standard form of 0.00000012 = 1.2  × $10^{-7}$m

Step-by-step explanation:

Given,

The average diameter of Corona virus-cell = 0.00000012

Required to find,

The standard form of 0.00000012

Recall the concept

The standard form of a number is obtained by writing the number in the form a ×$10^n$, such that  1≤p<10 and 'n' is an integer.

Solution:

Given number is 0.00000012

To get the standard form we should move the decimal places 7 places to the right.

So we need to multiply and divide the number with $10^{7}$

0.00000012  = 0.00000012 × $\frac{10^7}{10^7}$

=$\frac{1.2}{10^7}$

=1.2  × $10^{-7}$

0.00000012  = 1.2  × $10^{-7}$

Hence the standard form of 0.00000012 = 1.2  × $10^{-7}$m
