Certainly! Let's find the product of the expression:

[tex]\[ (3 a^2 b^7)(5 a^3 b^8) \][/tex]

We will proceed step-by-step to simplify the expression.

Step 1: Multiply the coefficients.
The coefficients in the given expression are [tex]\(3\)[/tex] and [tex]\(5\)[/tex]. Multiplying these gives:
[tex]\[ 3 \times 5 = 15 \][/tex]

Step 2: Apply the Laws of Exponents to [tex]\(a\)[/tex] and [tex]\(b\)[/tex].

- For the term involving [tex]\(a\)[/tex]:

[tex]\[ a^2 \times a^3 = a^{2+3} = a^5 \][/tex]

- For the term involving [tex]\(b\)[/tex]:

[tex]\[ b^7 \times b^8 = b^{7+8} = b^{15} \][/tex]

Step 3: Combine the results from the above steps.
Bringing everything together, we have:
[tex]\[ 15 a^5 b^{15} \][/tex]

Therefore, the product of the expression [tex]\((3 a^2 b^7)(5 a^3 b^8)\)[/tex] is:

[tex]\[ 15 a^5 b^{15} \][/tex]

So the correct answer is:

[tex]\[ \boxed{15 a^5 b^{15}} \][/tex]
