Cine poate să mă ajute?​

Answer 1

5.

$a=3.5\cdot \:0.2+2020.2^0\\a=0.2\cdot \:3.5+1\\a=0.7+1\\a=1.7$

$b=\frac{41.5}{100}+1.5^2\\b=\frac{41.5}{100}+2.25\\b=0.415+2.25\\b = 2.665$

Astfel, $a < b$

6.

$231.18-x=56.354\\231.18-x=56.354-231.18\\-x=-174.826\\x=174.826$

7.

$54.7+54.7+13.9=123.3\\178-123.3=54.7$
