The sum of the k for k=1 to k="n"=(n*(n+1))/2 , where "n" is the total integer.

In this problem n = 200

Sum = (200*201)/2 = 20,100

zvonat [6]

Answer:

12 x^5y^12

Step-by-step explanation:

3x^2y^5 * 4x^3y^7

Multiply the constants

3*4 = 12

Multiply the x terms

x^2 * x^3

We know a^b* a^c = a^(b+c)

x^(2+3) = x^5

Multiply the y terms

y^6 * y^7 = y&(5+7) = y^12

Put them back together

12 x^5y^12
