M and N are monomials in 3x · (m-5x) = 6x ^ 2 · y ^ 3 + n Finding the value of M and n The difference between 3x and (m-5x) is 6 times the square of x times the third power of y plus n

M and N are monomials in 3x · (m-5x) = 6x ^ 2 · y ^ 3 + n Finding the value of M and n The difference between 3x and (m-5x) is 6 times the square of x times the third power of y plus n

3xM=6x^2y^3
3x(-5x)=N
therefore
M=2xy^3
N=-15x^2

It doesn't matter if the answer is wrong! But it's better to be right!

-1/2 2
The square of X, the square of 2XY, the square of - y, 2
（a+b) (2a+4b)

What is the coefficient of the binomial - 3 squared by a squared by B squared by C? Is it - 3 squared or - 3?

The square of - 3 = 9, the letter after it doesn't care, just look at the number. So it's 9

Find the degree of a monomial,
The fourth power of X is multiplied by y
The denominator is 4 and the numerator is the fourth power of X multiplied by y
What's the number of times?
I just learned this, but I don't understand it very well
This is the fourth power * y decomposed into four parts of X. I think the fourth power of X in the fourth power of four parts of X should not be included in the number of times. Is its number 1 correct? Or is the fourth power of X also included?
If it's not right, I hope the kind-hearted people can be reasonable (╯▔▽▔) ╯

The fifth power is the sum of the times of all unknowns

2. A yuan for each pen and B yuan for each pencil. How much should Xiao Ming pay for three pens and two pencils?
These are two questions to fill in the blanks

1÷(1/a+1/b)
=AB / (a + B0 days)
3A + 2B yuan
