Question

Write the value of 48^3-30^3-18^3

Answer 1

Answer:

77760 is the answer

Step-by-step explanation:

$(48) {}^{3} + ( - 30) {}^{3} + (18) {}^{3}$

We know that,

if a+b+c=0

or, 48-30-18=0

then

$a {}^{3} + {b}^{3} + c {}^{3} = 3abc$

Let a=48. b= -30. c= -18

$3abc=3\times48\times(-30)\times(-18)$

=77760
