Question

___ are the symbols that perform an operation on the constants or reference to yield a result​

Answer 1

Answer:

(i) In 2a, 2 is a constant and a is a variable.

(ii) In -7mn, -7 is a constant and m and n are variables.

(iii) In 3x, 3 is constant and x is variable but together 3x is a variable.

(iv) If 3 is a constant and x is a variable, then 3 + x, 3 - x, 3/x, 3x, x/3, etc., are also variables.

So, we conclude that the combination of a constant and a variable is always a variable.
