Consider the numerical expression: 3^4 If the given expression is raised to the power of 12, which expression is NOT equivalent?
A)3^16
B)3^48
C)(3^12)^4
D)(3^6)^8

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
