Answer :

Sure! Let's solve the expression [tex]\(12a^8 - 15^2 c^2\)[/tex] step by step.

### Step 1: Calculate [tex]\(15^2\)[/tex]
First, we need to square 15:
[tex]\[ 15^2 = 225 \][/tex]

### Step 2: Express the problem with the calculated value
Replace [tex]\(15^2\)[/tex] with 225 in the original expression:
[tex]\[ 12a^8 - 225c^2 \][/tex]

### Step 3: Simplify
Since there are no further operations needed and the terms cannot be combined (as they have different variables and exponents), the simplified expression is:
[tex]\[ 12a^8 - 225c^2 \][/tex]

Thus, the detailed step-by-step solution to the expression [tex]\(12a^8 - 15^2c^2\)[/tex] is:
[tex]\[ 12a^8 - 225c^2 \][/tex]
