Answer:

? = 14

Step-by-step explanation:

If ∆EFG ~ ∆CBA, we have the proportion

FG/FE = BA/BC . . . . . any pairs of corresponding sides will have the same ratio for similar triangles. (It is convenient to put the unknown in the numerator.)

?/18 = 21/27 . . . . . . filling in the given numbers

Multiplying by 18, we have ...

? = 18·21/27

? = 14

_____

If the triangles are not designated as being similar, the problem is unworkable.

I think it’s 104,974
Because PEMDAS,
so first deal with exponents and 3 to the fourth power is 81. 6 to the fourth power is 1,296.
Next in PEMDAS is multiplication and division, so 1,296 times 81 is 104,976. Then 4 divided by 2 is 2.
Finally comes subtraction, 104,976 minus 2 = 104,974
