To evaluate a–4b2 for a = –2 and b = 4, substitute the given values into the expression:
(–2)–4(4)2
=(-2)^-4 * 4^2
Now, simplify the expression step by step:
=(-1/2)^4 * 16
= (1/(2^4)) * 16
= (1/16) * 16
= 1
The correct answer is: 1
(–2)–4(4)2
=(-2)^-4 * 4^2
Now, simplify the expression step by step:
=(-1/2)^4 * 16
= (1/(2^4)) * 16
= (1/16) * 16
= 1
The correct answer is: 1
