The first step to solving this is to write the number in exponential form
2

=

since the bases are the same,, set the exponents equal to one another
-IxI = 7
now change the signs on both sides of the equations
IxI = -7
this equation is false for any value of x because the absolute value function needs to always be positive or 0,, which is not the case for this expression
x ∈ ∅
this means that the answer to your question is x ∈ ∅
let me know if you have any further questions
:)
For A, the volume is 2 x 1 x 7 = 14
for B, the volume is 3 x 3 x 2 = 18
so B has a greater volume
please give brainliest! thanks, :D
