Order of Operations is what you have to use
Yes, 6/8 reduces to 3/4 by dividing the numerator and denominator by 2.
Answer: [H+] = 10^-7.2
Step-by-step explanation:
Given that the PH of the solution = 7.2
Using the formula pH = –log[H+]. To get the H+ concentration from the pH, raise both sides by the base of 10. Then we have
10^ -pH = H+. with pH of 7.2,
Thus the answer to this problem is
[H+] = 10^-7.2
Note that for negatives, flip the place of the number, and change the power to positive
4^-3 = 1/(4³)
Multiply
1 x 4² = 4²
Divide. Note that when dividing powers with the same base, subtract the powers
4²/4³ = 1/4
1/4 is your answer
