Question

if z = 0.0064 find the value of (1/z)^1/2

Answer 1

Answer:

Z=0.0064

(1/z)^1/2 = 1/z^1/2

             = 1/√0.0064

             = 1/0.08

              = 12.5

Answer 2

Answer:

12.5

Step-by-step explanation:

$\bigg(\dfrac{1}{z}\bigg)^\frac{1}{2}$

Given that z = 0.0064

$\bigg( \dfrac{1}{z} \bigg)^\frac{1}{2} = \bigg( \dfrac{1}{0.0064} \bigg)^\frac{1}{2}$

Write 0.0064 as (0.08)²

$\bigg( \dfrac{1}{z} \bigg)^\frac{1}{2} = \bigg( \dfrac{1}{0.08^2} \bigg)^\frac{1}{2}$

Evaluate the exponent:

$\bigg( \dfrac{1}{z} \bigg)^\frac{1}{2} = \dfrac{1^\frac{1}{2}}{(0.08^2)^\frac{1}{2}}$

$\bigg( \dfrac{1}{z} \bigg)^\frac{1}{2} = \dfrac{1}{0.08}$

Divide:

$\bigg(\dfrac{1}{z}\bigg)^\frac{1}{2} = 12.5$

Answer: 12. 5
