In the expression 5n- 2m/7 + 3/4, what is the constant?<br> A. -2/7<br> B. 3/4<br> C. 5<br> D. 21
gavmur [86]

Answer:

Step-by-step explanation:

For this case we have the following expression:

 5n-2m / 7 + 3/4

 We have the following variables:

 variable 1: n

 variable 2: m

 The terms that accompany the variables are coefficients

 Therefore, the term that does not accompany the variables is the constant of the expression.

 The constant is: 3/4

 Answer:

 the constant is 3/4

Evaluate the indefinite integral. (Use C for the constant of integration.)
IceJOKER [234]
\displaystyle\int\frac{(\ln x)^{44}}x\,\mathrm dx

y=\ln x\implies\mathrm dy=\dfrac{\mathrm dx}x

\displaystyle\int y^{44}\,\mathrm dy=\frac{y^{45}}{45}+C

\displaystyle\int\frac{(\ln x)^{44}}x\,\mathrm dx=\frac{(\ln x)^{45}}{45}+C
