Question

Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8 ?

Answer 1

Answer:

2.3 × $10^{-4}$ is 20,000 times greater than 1.15 × $10^{-8}$

Step-by-step explanation:

Given as :

The first number= x = 2.3 × $10^{-4}$

The second number= y = 1.15 × $10^{-8}$

Let The first number is z times greater than second number

i.e x = z × y

Or, z = $\dfrac{x}{y}$

Or, z = $\dfrac{2.3\times 10^{-4}}{1.15\times 10^{-8}}$

Or, z = 2 × $10^{4}$

∴  z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 × $10^{-4}$ is 20,000 times greater than 1.15 × $10^{-8}$ . Answer
