Question

If ∆ is an operation such that for integers m and n ,we get m∆ n= m*m*m+n*n*n-3*m*n,then find (-4)∆5

Answer 1

Answer:

121

Step-by-step explanation:

((−4)(−4))(−4)+(5)(5)(5)−(3)(−4)(5)

=(16)(−4)+(5)(5)(5)−(3)(−4)(5)

=−64+(5)(5)(5)−(3)(−4)(5)

=−64+(25)(5)−(3)(−4)(5)

=−64+125−(3)(−4)(5)

=61−(3)(−4)(5)

=61−(−12)(5)

=61−(−60)

=121
