-3 = x²

square root both sides to make x the subject of the formula

√-3 = √x²

damaskus [11]

Given:

Schaum's earnings in a month = $x^4+16x$

His wife's earnings in a month = $3x^4+11x$

Solution:

We know that,

Total earnings = Schaum earnings + His wife's earnings in a month

$=4x^4+27x$

Therefore, the correct option is A.
