-48
Order of operation is key. Square first. 4 squared is 16. then multiply 16x-3= -48. A negative times a positive is a negative.
-sqrt(48/3) = -sqrt(16) = -4 Technically, sqrt(16) = +4 or -4 so -sqrt(16) = -4 or +4

-30/48 - 8/48 = -38/48 or -19/24

It is a <= -48
Negative 48 volt DC voltage is simply a voltage that is negative 48 volts with respect to ground. This voltage is widely used in telecommunication systems.
The question is incomplete. If the phrase between "but" and "equals" is "sums to" or something equivalent, then the answer is -9.2111 and +5.2111, approx.
16?
