Question

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

Answer 1

2.3x10^-4 is approximately 20000 times greater than 1.15x10^-8.

Step-by-step explanation:

To find out how many times greater 2.3x10^-4 is than 1.15x10^-8, we need to divide the two numbers. The formula for dividing two numbers in scientific notation is to divide the coefficients and subtract the exponents. So, (2.3 / 1.15) x 10^(-4 - (-8)) = 2 x 10^4 = 20000.

Therefore, 2.3x10^-4 is approximately 20000 times greater than 1.15x10^-8.

Answer 2

2.3 × is 20,000 times greater than 1.15 ×

Step-by-step explanation:

Given as :

The first number= x = 2.3 ×

The second number= y = 1.15 ×

Let The first number is z times greater than second number

i.e x = z × y

Or, z =

Or, z =

Or, z = 2 ×

∴ z = 20,000

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

Hence, 2.3 × is 20,000 times greater than 1.15 ×
