Answer:
Option B.
Step-by-step explanation:
Let as consider the given equation:
It can be written as
![[\because \ln e^a=a]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ea%3Da%5D)
![[\because \ln a^b=b\ln a]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20a%5Eb%3Db%5Cln%20a%5D)
![[\because \ln \dfrac{a}{b}=\ln a-\ln b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20%5Cdfrac%7Ba%7D%7Bb%7D%3D%5Cln%20a-%5Cln%20b%5D)
On comparing both sides, we get
Multiply both sides by 5.
Divide both sides by 2.
Therefore, the correct option is B.
If 61 is less than 8 times the number then the number is 8.
Given 61 is 3 less than 8 times the number.
Let the number be 'x'.
The term "polynomial" in mathematics refers to a mathematical statement that consists of two or more algebraic terms that are added, subtracted, or multiplied (no division!). Constants and positive exponents are frequently used, together with at least one variable, in polynomial formulas.
we can write the equation as:
8x ₋₋ 3 = 61
arranging the like terms i.e constants.
8x = 61 ₊ 3
8x = 64
to find the value of x, divide 64 by 8.
x = 64 ÷ 8
x = 8
hence the number we get after solving the equation is 8.
