Answer:
x = 3
Step-by-step explanation:
Using the rules of logarithms
ln x = ln y ⇒ x = y
ln e = 1
Given
2 ln e ln 5x = 2 ln 15 ( divide both sides by 2 )
ln e ln 5x = ln 15
ln 5x = ln 15, hence
5x = 15 ( divide both sides by 5 )
x = 3
<span>Analogicaly as in the previous question - firstly let's find the common denominator for those fractions:
2/3 = 12/18
2/9 = 4/18
5/6 = 15/18
11/18 = 11/18 :)
From the least to the greatest:
2/9, 11/18, 2/3, 5/6</span>
Answer:
These are actually pretty easy. So the dots represent 1, hours. The correct answer would be the one under the first box, the one with the first blue box right below the 8 but above the 6. Mark as brainliest, this is correct!
15 = 3² +2(7-4)
____
The above expression includes operations of
- exponentiation
- subtraction
- multiplication
- addition
The exponent is 2.
I know the value of this expression is 15 because
- I designed the expression to have a value of 15
- I get a value of 15 when I evaluate the expression
- A reliable on-line calculator also gets a value of 15 when it evaluates the expression
