Express the following in algebraic
form: the square of a number π which is then multiplied by 19.
In this question, our variable is
the letter π. Weβre asked to square this, which
is written as π to the power of two. Our exponent of π is two. We then need to multiply π squared
by 19. In its simplified form, this is
written 19π squared. When writing the product of a
constant and a variable, we always write the constant first. The square of a number π which is
then multiplied by 19, in algebraic form, is 19π squared.
