Thank you !
In the metric system, you give a name to the following multiples: 10, 100, 1000, 0.1, 0.01, 0.001, and then you skip three places. So, you have
And thus 0.000001 of something is a micro-something (i.e. one millionth of a certain unit)
The solution to the algebraic expression is: 23e - 21g - 14j + 32
What are algebraic expressions?
Algebraic expressions are mathematical expressions that contain variables, coefficients, and arithmetic operations such as addition, subtraction, division, and multiplication.
Solving algebraic expressions are an important part of mathematics as it helps to improve the aptitude and solving skills of the students.
From the given information, we have;
23j - 21g + 20e - 13 + 52e - 37j + 45 - 49e
let's rearrange by taking the like terms to the same sides;
= 23j -37j - 21g + 20e + 52e - 49e - 13 + 45
= -14j - 21g + 23e + 32
= 23e - 21g - 14j + 32
Therefore, we can conclude that the solution to the algebraic expression is: 23e - 21g - 14j + 32

Answer:
u * v = 39 ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- u and v are two vectors
- u * v means the scalar product of the two vectors
- The scalar product is a way of multiplying vectors
- The result of a scalar product is always a number not a vector
- Ex: If u = ai + bj ⇒ <a , b> and v = ci + dj ⇒ <c , d> then the scalar
product of them is ac + bd where ac + bd is a number
* Lets solve the problem
∵ Vector u = 13j ⇒ <0 , 13>
∵ Vector v = i + 3j ⇒ <1 , 3>
- Lets find the scalar product
∴ u * v = (0)(1) + (13)(3)
∴ u * v = 0 + 39
∴ u * v = 39
