30 POINTS WHO CAN HELP ME WIHT THIS <3 You have to put 1,2,3,4,5,6 in every row and column (NO REPEATS!), but also so you get the number in each box using +,-,x or divide.
Example: top left it says 11+. The box has two spaces, so you need two numbers that add up to 11. So the only option is 5 and 6. But you don't know which way round yet, so you must look at some other boxes first.

d

step-by-step explanation:

d

we are given expression: and .

in order to find it's greatest common factor, let us break it into smaller parts.

let us find greatest common factor of 54 and 27 first.

54 = 27 × 2

27 = 27 × 1

now, let us find the greatest common factor of m and m^3.

now, let us find the greatest common factor of n^4 and n^2.

therefore, following expressions are part of the greatest common factor of 54mn^4 and 27m^3n^2.
