Question

De maneira semelhante resolva as expressões :

a) 3/4 - ( 7/16 × 4 - 3/4)x^{6} + \sqrt{1/81}

b ) 7/3 + 4964 ÷ 21\8 - ( 3\8 × 16\9)x^{2}

Urgente!

Answer 1

A)

3/4 - (7/16*4-3/4) x^6 + √1/81

3/4-(28/16 - 3/4)x^6+√1/81

3/4 -(7/4 - 3/4)x^6+√1/81

3/4-1*x^6+√1/81

3/4-1*x^6+√1/√81

3/4-1*x^6+1/9

3/4-x^6+1/9

-x^6+(3/4+1/9)

31/36 -x^6

==========================================================

B)

7/3 + 4964 ÷ 21/8 - ( 3/8 * 16/9)x^2

7/3+4964/21/8 -3*16/8*9 x^2

7/3+4964/21/8- 48/72 x^2

7/3+4964/21*8-48/72 x^2

7/3+4964/168 -48/72 x^2

7/3 +1241/42 - 48/72 x^2

7/3+1241/42-2/3 x^2

7/3+1241/42-2x^2/3

-2x^2/3+ (7/3+1241/42)

-2x^2/3+1349/42
