7 less than k
k is a variable, 6 is a coefficient.
A constant.
y=x^2 * k k=constant of proportionality OR y/x^2 = k
Basically, in an exponential expression (or equation) you have the independent variable in the exponent. For example: 5 times 10x The general form of an exponential function can be written as: abx or: aekx where a, b, and k are constants, and e is approximately 2.718. Note that just having a power doesn't mean you have an exponential equation. For example, in x3 the variable does NOT appear in the exponent, so it is not an exponential expression.

7 less than k
k = 10 3k = 30 When a number appears next to a variable (like "k") it usually means multiply the number times the variable.
You have not told us what expression you wish to simplify.
The generic expression for this type of question is as follows: cx * x = cx2 Where c is a constant, and x is a variable. So 4k * k = 4k2.
Any rational number of the form 5k/8k where k is an integer is equivalent.
K can be a variable, it is commonly a variable in the quadratic equation y=a(x-h)2+k K is the y-intercept.
The variable is k.
k is a variable, 6 is a coefficient.
2k/3 - 4
k is the variable.
