Question

Jika a= 5, b=7 dan c=8. nilai 2a²-3b³+4c⁴ adalah

Answer 1

= 2 ( 5 x 5 ) - 3 ( 7 x 7 x 7 ) + 4 ( 8 x 8 x 8 x 8 )
= 2 (25) - 3 (343) + 4 ( 4096 )
= 50 - 1029 + 16384
= 15.405 

Answer 2

{2×(5×5)}-{3×(7×7×7)}+{4×(8×8×8×8)}
(2×25) - (3×343) + (4×4096)
100 - (1029 + 16384)
100 - 17413 = - 10313
