The value of the expression when a = 2 and b = -4 is 5
Evaluating an expression
From the question, we are to determine the value of the expression for the given values of a and b
The given expression is
√(a³ -7) + |b|
From the given information,
we are to determine the value of the expression, when a = 2 and b = -4
Putting the values of a and b into the expression, we get
√((2)³ -7) + |-4|
√(8 -7) + 4
√(1) + 4
1 + 4
= 5
Hence, the value of the expression when a = 2 and b = -4 is 5
