Answer:
c .3.3
Step-by-step explanation:
pH is the negative log of the molar hydrogen ion concentration.The equation to calculate pH is;
pH = -log10[H+]
pH = -log10(5.0 x 10-4)
pH = 3.30
The given question is wrong.
Question:
Brandi solved
by using a related multiplication expression. What multiplication expression did she is?
Answer:
The related multiplication expression is
.
Solution:
Given expression is
.
We can write 5 as a fraction with denominator 1.
![$ \frac{1}{6}\div5=\frac{1}{6}\div \frac{5}{1}](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B1%7D%7B6%7D%5Cdiv5%3D%5Cfrac%7B1%7D%7B6%7D%5Cdiv%20%5Cfrac%7B5%7D%7B1%7D)
Using the fraction rule
,
![$\frac{1}{6}\div \frac{5}{1}=\frac{1}{6}\times \frac{1}{5}](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B6%7D%5Cdiv%20%5Cfrac%7B5%7D%7B1%7D%3D%5Cfrac%7B1%7D%7B6%7D%5Ctimes%20%5Cfrac%7B1%7D%7B5%7D)
Now multiply the fractions using the rule
,
![$\frac{1}{6}\times \frac{1}{5}=\frac{1\times1}{6\times5}](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B6%7D%5Ctimes%20%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B1%5Ctimes1%7D%7B6%5Ctimes5%7D)
Let us multiply the numbers in the numerator and denominator separately, we get
![$\frac{1\times1}{6\times5}=\frac{1}{30}](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%5Ctimes1%7D%7B6%5Ctimes5%7D%3D%5Cfrac%7B1%7D%7B30%7D)
Hence the related multiplication expression is
.
