-3•e^(2m-5)-3=-27 how to solve
1 answer:
Answer:
m = 3.53972077085
Step-by-step explanation:
-3 × - 3 = -27
Subtracting -3 from both sides of the equation gives;
-3 × = -24
Dividing by -3 on both sides of the equation gives;
= 8
Let 2m - 5 = x
xloge = 3log2
x = = 2.0794415417
So,
2m - 5 = 2.0794415417
2m = 2.0794415417 + 5
2m = 7.0794415417
Dividing by 2 on both sides of the equation gives:
m = 3.53972077085

<span><u><em>Answer:</em></u>
It represent the tens of the number, therefore, it's unit value is 30
<u><em>Explanation:</em></u>
The place value chart is added in the attached image.
<u>Checking this chart, we would find that:</u>
first digit from the right is the units of the number
second digit from the right is the tens of the number
third digit from the right is the hundreds of the number
Comparing this with the nuber given, we would find that the 3 is in the tens position. Therefore, it unit value is 30.
<u>Another way to answer this is by breaking the number given as follows:</u>
432 = 400 + 30 + 2
We can note that the unit value of the 3 is 30
Hope this helps :)</span>
