Question

Calcule o valor numerico das expressões seguintes para X=6 e Y=11 . ( simplifique antes)

a) x^5 y^5 / x³y^7

b) x^5 + x⁴y / 2x⁴

c) x²-y² / 17x - 17y

d) 3x + 3y / x² + 2xy + y²

Answer 1

a) x^5y^5/x^3y^7
x^3y^3(x^2y^2)/x^3y^3(y^4)
x^2y^2/y^4
y^2x^2/y^2y^2
x^2/y^2
6^2/11^2
36/121


b) x^5+ x^4y/2x^4
x^4(x+y)/2x^4
x+y/2
6+11/2
17/2


c)x^2-y^2/17x-17y

=0


d)3x+3y/x^2+2xy+y^2
3 (x+y)/(x+y)(x+y)
3/x+y
3/6+11
3/17
