Answer:
144
Step-by-step explanation:
You need to know the Order of Operations. First you do 2 to the power of 4 (because it's the E in PEMDAS) which is 2*2*2*2 which equals 4, 8, 16, then you would do three squared which is 3*3 which equals 9. Multiply (M in PEMDAS) 16 by 9 which would come out to 144 or how I would multiply those two numbers is 9*10 + 9*6 or 90 + 54 with a final answer of 144.
Well, if
{bx - 6y = 18 and {2x - 3y = 9, you might want to try elimination
Multiply second equation by -2: bx - 6y = 18 and -2(2x - 3y = 9)
Simplified: bx - 6y = 18 and -4x + 6y = -18
Now if you add them you get: -4x + bx = 0
Then simplified: bx = 4x
divide by x: b = 4
Your final solution is b = 4.
Hope that helps!
