Answer: a. 100 b. 27512
Explanation:
a. a = -2 and b = 3
by substituting a and b values in the given expression, we get
(a+4b)² = ((-2)+4(3))²
= ((-2)+12)²
= (10)²
= 100
b. (a²+8ab+166²)
by substituting a and b values in the given expression, we get
= ((-2)²+8(-2)(3)+166²)
= (4+8(-6)+27556)
= (4-48+27556)
= 27512
