Question

por favor necesito ayuda $28 : (3 ^{2} -5) + 2. \sqrt{64} = 2, \sqrt{25} - \sqrt{9} + \sqrt{16}+(20 + 4):3= 3, 24-6.4+(5-4).5^{2}- \sqrt{49}= 4, 5^{3}- ^{3}\sqrt{125}+ (7-2)^{2} -(6+39)^{2}=$

Answer 1

$28:(4)+2(8)=7+16=23$
$2,5-3+4+24:3 \\ 2,5-3+4+8 = 14,5-3=11,5$
$3,24-6,4+(1).25-7=28,24-13,4=14,84$
91,125-5+25-2025=-1903,875
