Answer 1

[Lê Minh Vũ]

\(48\div4+3^9\div3^7+5^0\)

\(=12+9+1\)

\(=22\)

\(\left(5^{19}\div5^{17}+3\right)\div7\)

\(=\left(25+3\right)\div7\)

\(=28\div7\)

\(=4\)

\(295-\left(32-2^2\times5\right)^2\)

\(=295-144\)

\(=151\)

\(6^2\div9+50\times2-3^3\times3\)

\(=36\div9+100-27\)

\(=4+100-27\)

\(=100-27\)

\(=73\)

48:4+39:37+50

=48:4+3²+1

=12+9+1=22

(519:517+3):7

=(5²+3):7

=(25+3):7

=28:7=4

295-(31-22.5)2

=295-(31-4.5)²

=295-(31-20)²

=295-11²

=295-121

=174

62:9+50.2-33.3

=36:9+50.2-3⁴

=4+100-81

=23
