Question

A triangle has an area equal to 1/2(12x^2y^2)(6x^3y^5). Which of the following expressions represents the simplified form of the area of this triangle?
Select one:
A. 72x^2y^2
B. 36x^5y^7
C. 36x^6y^10
D. 36x3^y^6

Answer 1

@hoblos could you help?

Answer 2

multiply the numbers and add the powers of like variables
so (1/2)*12*6 = 36

x^(2+3)
y^(2+5)

you get 36x^5y^7

Answer 3

so you just add up the exponents?

Answer 4

yes
(x^a)(x^b) = x^(a+b)
