What does it mean with a less than sign with a line under it

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

current in the circuit at time t is /, then the power delivered to the resistor is

step-by-step explanation:

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya
