Remove the radical by raising each side to the index of the radical.
x=-1
Answer:
B.
Step-by-step explanation:
B. Because the others have exponents whose denominators are even so the results of , for example x^1/2, if x is negative is not defined.
For example:
For A, when x is -4, (-4)^1/2 is not real.
For B, when x = -4, (2*-4)^ 1/3 = -8^(1/3) = = -2.
Answer:
the cost for each drink = $2.54
Step-by-step explanation:
The statement formed a simultaneous equation :
3x + 6y = $21.12
4x + 9y = $30.41
solving simultaneously,you have that ; x = 2.54, y = 2.25
