$a^{-n}=\dfrac{1}{a^n}\\\\2^{-8}=\dfrac{1}{2^8}\\\\a^n\cdot a^m=a^{n+m}\\\\2^5\times2^1=2^{5+1}=2^6\\\\2^5\times2^{-8}\times2^1=\boxed{\dfrac{2^6}{2^8}}$

Please help, I miss one day and I dont know how to do this

valentinak56 [21]

Answer:

X is 12 Y is 124

Step-by-step explanation:

left and right side have equal degrees of 56

so x would be 12 because you would multiply 4×12

since in total it will be 360 degrees

you add 56 and 56 together to get 112

then just subtract 112 from 360 and you get 248 then divide 248 by 2 and you have your bottom and top value of 124
