aratati ca numarula=25%din 144 si b=(1/3+1/2+4/5)×30 sunt patrate perfecte​

Answer 1

Salut!
25% din 144 este 36. 36 este 6*6, deci acesta e patrat perfect.
(1/3+1/2+4/5)*30 este 49. 49 este 7*7, deci si acesta e patrat perfect.
Seara faina!

Answer 2

$\frac{25}{100} \times 144 = \frac{25 \times 144}{100} = \frac{3600}{100} = 36$

✓36=6==>36=6² patrat perfect

$( \frac{1}{3} {}^{ \times 10} + \frac{1}{2} {}^{ \times 15} + \frac{4}{5} {}^{ \times 6} ) \times 30 = \\ \\ \frac{10 + 15 +24 }{30} \times 30 = \\ = 10 + 15 + 24 = \\ = 49$

✓49=7 ==>49=7² patrat perfect
