8^7 * 8^2 = 8^9 = 134,217,728.
To solve the expression 8^7 * 8^2, we use the rule of exponents called the product of powers.
According to this rule, when multiplying two exponential expressions with the same base, you keep the base the same and add the exponents together.
In this case, we have 8^7 * 8^2. Since both expressions have the base 8, we can keep the base 8 and add the exponents 7 and 2 together.
So, 8^7 * 8^2 = 8^(7+2) = 8^9.
Therefore, the simplified expression is 8^9.
