Introduction

In this article, we will evaluate the expression ${$ (8+t)^3-6$}$ when ${$ t=2$}$. This involves substituting the value of ${$ t$}$ into the expression and simplifying the resulting expression. We will use basic algebraic operations and properties of exponents to simplify the expression.

Substituting the Value of ${$ t$}$

To evaluate the expression, we need to substitute the value of ${$ t$}$ into the expression. In this case, we are given that ${$ t=2$}$. We will replace ${$ t$}$ with ${ $2\$}$ in the expression.

Evaluating the Expression

Now that we have substituted the value of ${$ t$}$, we can evaluate the expression. We will start by expanding the cube of the binomial ${$ (8+t)$}$.

Expanding the Cube of the Binomial

To expand the cube of the binomial ${$ (8+t)$}$, we will use the formula ${$ (a+b)^3=a3+3a^2b+3ab2+b^3$}$. In this case, ${$ a=8$}$ and ${$ b=t$}$.

Applying the Formula

Applying the formula, we get:

${$ (8+t)³⁼⁸3+3(8)^2(t)+3(8)(t)2+t^3$}$

Simplifying the Expression

Now, we can simplify the expression by evaluating the powers of ${ $8\$}$ and ${$ t$}$.

${$ (8+t)^{3=512+3(64)(t)+3(8)(t)}2+t^3$}$

${$ (8+t)^{3=512+192t+48t}2+t^3$}$

Substituting the Value of ${$ t$}$

Now that we have simplified the expression, we can substitute the value of ${$ t$}$ into the expression.

${$ (8+t)^{3=512+192(2)+48(2)}2+(2)^3$}$

Evaluating the Expression

Now, we can evaluate the expression by performing the arithmetic operations.

${$ (8+t)^3=512+384+192+8$}$

${$ (8+t)^3=1096$}$

Subtracting 6 from the Result

Finally, we need to subtract 6 from the result to get the final answer.

${$ (8+t)^3-6=1096-6$}$

${$ (8+t)^3-6=1090$}$

The final answer is $\boxed{1090}$ .
