1) What is the value of 19 + 5a^4 + 3b^2 when a = 2 and b = 4?
(this is not a multiple choice question) but my answer is 147.
2)Combine the like terms to simplify the expression: 4 + 7xy^2 + 5y^3 + 10x 4xy^2  8x  4y^3 + 9
 y^6 + 3x^2y^2 + 10x + 13
 y^3 + 3xy^2 + 2x + 13
 y^3 + 3xy^2 + 10x + 13 *my answer*
 y^3  3xy^2 + 2x + 9
3) Which is equal to 4^2 x 4^8
 4^16
 4^10 *my answer*
 4^6
 4^6

1) 19 + 5 (16) + 3(16) = 19 + 80 + 48 = 147 (agree)
2) y^3 + 3xy^2 + 2x +13
10x 8x = 2x
3) Right
