I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20
--------------------------------------------
So that's how we're able to go from this
to this 
The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.

<u>Answer: </u>
The value of the exponential expression is 2
<u>Solution:</u>
16 superscript one-fourth=
As per the problem,
We have to find the value of
16 in terms of 2 can be written as
=
=
As per the exponential rule,
=
Here,
=
= 2
Hence, the value is 2.
