Answer: The expression, 3v^4, means that the variable, v, is multiplied by itself 4 times (v * v * v * v) and then is multiplied after by the coefficient 3.
Explanation:
Exponent indicates the number of times a number needs to be multiplied by itself.
For example if your given x^2
that simply means that the variable, x, is being multiplied by itself twice:
x * x
if your given 2z^9
that means that the variable, z, is first multiplied by itself nine times and after that it is multiplied by the coefficient, two.
