Question

(√5⁴ - 5²)³ ÷ (6 + 12 • 2)

Answer 1

$\frac{(\sqrt{5^4}-5^2)^3}{6+12.2}=\frac{(\sqrt{5.5.5.5}-5.5)^3}{6+24}=\frac{(\sqrt{625}-25)^3}{30}=\frac{(25-25)^3}{30}=\frac{0^3}{30}=\frac0{30}=0$

Answer 2

= (√5⁴ - 5²)³ : (6 + 12.2)

= (√625 - 25)³ : ( 6 + 24)

= (25 - 25)³ : 30

= 0³: 30

= 0 : 30

= 0
