Answer 2

We know that,

m = 2 and n = 5

We have to find the value of,

2 m³ + 3 n² -31                                        ---------------------(1)

Solution,

Putting the value of m and n in the eq (1),

Then,

2 (2)³ + 3 (5)² - 31

By solving it,

we get,

2 (8) + 3 (25) - 31

16 + 75 - 31

91 - 31

60

Hence the answer is,

60
