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‘˜. We’re 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.
