1- sqrt((52+(2/3)2) Calcuator order of operations practice. Try to punch this in a single sequence. 2- tan-1(3/4) = (in degrees) Calcuator order of operations practice. Try to punch this in a single sequence.

Solution

1 - sqrt((52+(2/3)2)

= 1 - sqrt(52+ 4/3)

= 1 - sqrt((156 +4)/3)

= 1 - sqrt(160/3)

= 1 - 4sqrt(10/3)

b) 2- tan^-1(3/4)

= 2 - 0.6435

= 1.3565 radians

= 1.3565 * (180 /pi) degrees

= (1.3565/pi) (180) degrees

= 0.4317874 * 180 degrees

= 77.722 degrees
