Hint: A verbal expression is a mathematical statement that is expressed that is expressed in words. Or in other words we can say that a verbal expression uses words to decipher the mathematical information. In a problem an equation can often be written from a verbal method. Algebraic expressions don’t contain equal signs. Use subtraction in place of $\left( - \right)$ in the algebraic expression into verbal expression.

Complete step by step solution:
In this we have to write algebraic expression into the verbal expression.
The algebraic expression we have $7{{x}^{3}}-1$
First we will write the verbal expression for $7{{x}^{3}}$. This the multiplication of a constant and a term with an exponent.
So, we can write.
The product of $7$ and $n$ cubed.
Next is subtraction or a ‘difference’
So we can write.
The difference of the product of $7$ and $x$ cubed and $1.$
We can also write this as a sum using a negative number.

The sum of the product of $7$ and $x$ cubed and minus $1.$

For ex. $\dfrac{90}{D}-8$
