express the area of each triangle as a monomial.
11. height- 4ab^5

area = (1/2) base*height
10. (1/2)(5 n^3)(2 n^2)
to multiply, add exponents
11. (1/2) (3 a^4 b^1)(4 a^1 b^5)
6 a^(4+1) b^(1+5)
6 a^5 b^6

yes but in the first one (#10) the 1/2 and the 2 is not included. I don't know what to do with that.

Oh, do the arithmetic separately
(1/2)(5) (2) = 5

In the second one it is
you could say that is
but I looked at it and said to myself ---half of four is two, so it is two times three or 6
