The half price of helium-5 is 7.6 X 10 to the power of negative 22 seconds and the half-life helium -9 is 7 x 10 to the power of

Digiron [165]

Answer:

Approximately 9.211 times

Step-by-step explanation:

Given

$x = 7.6 * 10^{-22}s$ --- half life of helium-5

$y = 7 * 10^{-21}s$ --- half life of helium-9

Required

How many times greater is y than x

To do this, we simply divide y by x

$\frac{y}{x} = \frac{7 * 10^{-21}s}{7.6 * 10^{-22}s}$

$\frac{y}{x} = \frac{7 * 10^{-21}}{7.6 * 10^{-22}}$

Apply law of indices

$\frac{y}{x} = \frac{7 * 10^{-21--22}}{7.6}$

$\frac{y}{x} = \frac{7 * 10^{-21+22}}{7.6}$

$\frac{y}{x} = \frac{7 * 10}{7.6}$

$\frac{y}{x} = \frac{70}{7.6}$

$\frac{y}{x} = 9.211$

<h3>What is a Calculator?</h3>

This refers to the mathematical tool that is used to make scientific calculations to find an expected result and is fully automated.

Hence, we can see that calculator shortcuts in a Windows OS exists and some of them include the combination of keys on a keyboard for quick actions such as clearing and recalling from memory, among many others.
