Answer:
2/5of a number is 80 5/5 = 1 32/1 = simplified = 32
3/4 of the same number 0.75
For this case we must find the value of the following expression:

When:

Substituting the given values we have:

Finally, the value of the expression is 394.
Answer:
The value of the expression is 394.
Right side:
(1/27)^(2x+10)
=(3^-3)^(2x+10)
= 3^(-6x - 30)
Re-write both sides:
3^(4x-5) = 3^(-6x - 30)
from here, you can solve x
4x - 5 = -6x - 30
4x + 6x = -30 + 5
10x = -25
x = -2.5
The correct answer might be A
