Answer 3

To solve the expression $(2x + 3)^3$ using the formula, you can use the formula for the cube of a binomial, which is:

$(a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3$

In this case, $a = 2x$ and $b = 3$. Now, let's substitute these values into the formula:

$(2x + 3)^3 = (2x)^3 + 3(2x)^2(3) + 3(2x)(3)^2 + 3^3$

Now, simplify each term:

$(2x)^3 = 8x^3$

$(2x)^2 = (2x) \cdot (2x) = 4x^2$

$3(2x)^2(3) = 3 \cdot 4x^2 \cdot 3 = 36x^2$

$3(2x)(3)^2 = 3 \cdot 2x \cdot 9 = 54x$

$3^3 = 27$

Now, put everything back together:

$(2x + 3)^3 = 8x^3 + 36x^2 + 54x + 27$

So, the expression $(2x + 3)^3$ when solved using the formula is $8x^3 + 36x^2 + 54x + 27$.
