How do I simplify this? Include steps. " id="TexFormula1" title=" (\frac{5i^3t^4}{7})-2 " alt=" (\frac{5i^3t^4}{7})-2 " align="absmiddle" class="latex-formula">

Answer 1

Simplify the following:
(5 i^3 t^4)/7 - 2
i^3 = i^2×i = (-1) i = -i:
(5×-i t^4)/7 - 2
Put each term in (5 (-i) t^4)/7 - 2 over the common denominator 7:
(5 (-i) t^4)/7 - 2 = (-5 i t^4)/7 - 14/7:
(-5 i t^4)/7 - 14/7
(-5 i t^4)/7 - 14/7 = (-5 i t^4 - 14)/7:
Answer:  (-5 i t^4 - 14)/7
