calcular el valor numérico de las expresiones algebraicas siguientes, considerado.

a=2 b=5 c=3 d=-1 f=0

1) 6a³f

2)3a²-2a³+5a⁵

3) d⁴-d³-d²+d-1

4)3(a-b)+2(c-d)

5) c/3+b/5-a/2

6) 3/4a-2/5-1/2b+7/8f

7) 1/3f+d/b(a/b-c/f)


Les daré un ejemplo.

5a²-2bc-3d= 5(2)²-2(5)(3)-3(-1)
=5(4)-2(5)(3)-3(-1)
=20-30+3
=23-30
=-7 ​
