Simply each expression
(only do the ones that are underlined but you can do the rest if you’d like i guess)

a)  2^4 + 14*2 + 4 = 48

b) 9^2 + 3^2 (8-5)^2= 324

c) (5+3)^2 / (6-2) =16

d) 2^3 + 2(3*4)=8+2*12=32

e) 40/2^2 (4-2)^3 =80

f) (16-4)^2 4 + 3^2= 585

g) 10^2 -2[2(3*2)]=76

168

step-by-step explanation:

i am pretty sure that the answer is 168

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
