a) 36 : 32 + 23 . 22
= 34 + 25
= 81 + 32
= 113
b) (39 . 42 - 37 . 42) : 42
= 42 . (39 - 37) : 42
= 2
a) 36 : 32 + 23 . 22
= 34 + 25
= 81 + 32
= 113
b) ( 39 . 42 - 37 . 42 ) : 42
= ( 39 - 37 ) . 42 : 42
= 2 . 1
= 2
a) \(3^6:3^2+2^3\cdot2^2\)
\(=3^4+2^5\)
\(=113\)
b) \(\left(39\cdot42-37\cdot42\right):42\)
\(=\left[\left(39-37\right)\cdot42\right]:42\)
\(=\left(2\cdot42\right):42\)
\(=2\)
