Question

5. К сумме одночленов 4,64m3n и -9,02m3n прибавьте разность одночленов 2,02m3n и -3,36m3n. Помогите пожалуйстааа))

Answer 1

(4,64m3n+(-9,02)m3n)+(2,02m3n-(-3,36)m3n=-4,38m6n+5,38m=m6n

Answer 2

Adding and Subtracting Monomials

To find the sum of the monomials 4.64m^3n and -9.02m^3n, we add their coefficients and keep the variables unchanged. Similarly, to find the difference between the monomials 2.02m^3n and -3.36m^3n, we subtract their coefficients while keeping the variables the same.

The sum of 4.64m^3n and -9.02m^3n is: 4.64m^3n + (-9.02m^3n) = (4.64 - 9.02)m^3n = -4.38m^3n.

The difference between 2.02m^3n and -3.36m^3n is: 2.02m^3n - (-3.36m^3n) = (2.02 + 3.36)m^3n = 5.38m^3n.

Final Result

So, when we add the sum of the first pair of monomials to the difference of the second pair, we get: -4.38m^3n + 5.38m^3n = m^3n.
