To simplify 4/(2+7i), we multiply it by a fraction equal to one that removes the i value in the denominator. The best value to do this is the complex conjugate divided by itself, so we have 4(2-7i)/((2+7i)(2-7i)). Simplifying, we have (8-28i)/(4-(-49))=(8-28i)/53, which is a completely simplified fraction since 8 and 53 are relatively prime (or coprime), and there are no radicals in the denominator.

Step-by-step explanation:
179 and 180
consecutive numbers have a difference of 1 between them
let the 2 numbers be n and n + 1, then
n + n + 1 = 359
2n + 1 = 359 ( subtract 1 from both sides )
2n = 358 ( divide both sides by 2 )
n = 179 and n + 1 = 179 + 1 = 180
the 2 pages are 179 and 180
