Question

3 (4 na potencia de 2) - 4+5 =

3 (-2 na potencia de 2) -2+5=

3 ( 1/2 na potencia de 2) - 1/2+5=

3 (- 1/3 na potencia de 2) -1/3+5=

Answer 1

3 × (4²) - 4 + 5 =
3 ×16 +1 =
48 +1 = 49


3 × (-2²) - 2 + 5 =
3 × 4 + 3
12 + 3 = 15



3 × ( $\frac{1}{2}^2$) - $\frac{1}{2} + 5 = 3 × [tex] \frac{1}{4}$ - $\frac{1}{2} + 5 = [tex] \frac{3}{4}$ - $\frac{1}{2} + 5 = <strong>[tex] \frac{21}{4}$




3 ($-\frac{1}{3} ^{2}$) - $\frac{1}{3}$+ 5 =
3 × $\frac{1}{9}$ - $\frac{1}{3}$ + 5 =
$\frac{3}{9}$ - $\frac{1}{3}$ + 5 = 5
