Answer:
1 3/4
Step-by-step explanation:
First write the equation in mixed fraction form as;
1 3/4 + 1 1/3 = 1 _/12 + 1 4/12 ⇒ 7/4 + 4/3 = _ + 16/12
7/4 + 4/3 = _ + 16/12
37/12 = _ + 16/12
37/12 - 16/12 = _
= 21/ 12
= 1 9/12
= 1 3/4
Use index form. N= a^x becomes log a (N) = x
Therefore your question becomes (log 2.3 (13))/9 = x
And rounding to 3 decimals gives you 0.342
The answer to this is n= 4
