(59-6) x (⅓) ³ + 27 ÷ 3 =<br><br>8² ÷ 4 x (2 + 3) -9 =

luda_lava [24]

Answer:

(59-6) × $\sf{(\frac{1}{3})}^{3}$ + 27 ÷ 3

=53 × $\sf\frac{{1}^{3}}{{3}^{3}}$ + 3³ ÷ 3

=53 × $\sf\frac{1}{27}$ + $\sf{3}^{3-1}$

= $\sf\frac{53\times1}{27}$ + $\sf{3}^{2}$

= $\sf\frac{53}{27}$ + 9

=9 + $\sf\frac{53}{27}$ + 9

= $\sf\frac{9\times27+53}{27}$

= $\sf\frac{243+53}{27}$

= $\sf\frac{296}{27}$

= $\sf\frac{270}{27}+\frac{26}{27}$

= $\sf10+\frac{26}{27}$

= $\sf10\frac{26}{27}$

$\sf\:$

8² ÷ 4 × (2 + 3) - 9

=(8×8) ÷ 4 × 5 - 9

=64 ÷ 4 × 5 - 9

=4³ ÷ 4 × 5 - 9

= $\sf{4}^{3-1}$ × 5 - 9

=4² × 5 - 9

=(4×4) × 5 - 9

=16 × 5 - 9

=80 - 9

=71
