Evaluate (4p+q)raised to the second for p=5 and q=-4. Express the answer as a fraction.
16/1
[4(5)+-4]raised to 2nd
(20+-4)raised to 2nd
16 raised to 2nd
256 is the answer
To evaluate the expression (4p + q)² for p = 5 and q = -4, we need to substitute the given values into the expression and then simplify.
Substituting p = 5 and q = -4 into the expression, we get:
(4(5) + (-4))²
Simplifying within the parentheses:
(20 - 4)²
Now, simplify the subtraction within the parentheses:
(16)²
To square a number, we multiply it by itself:
16² = 16 * 16 = 256
Therefore, the value of (4p + q)², where p = 5 and q = -4, is 256.
Since you asked for the answer to be expressed as a fraction, we can write it as 256/1.
