Video Solution

Step-by-Step Solution

To simplify the expression (85)10\left(8^5\right)^{10}, we'll apply the power of a power rule for exponents.

  • Step 1: Identify the given expression.
  • Step 2: Apply the power of a power rule, which states that (am)n=amn(a^m)^n = a^{m \cdot n}.
  • Step 3: Multiply the exponents to simplify the expression.

Now, let's work through each step:
Step 1: The expression given is (85)10\left(8^5\right)^{10}.
Step 2: We will use the power of a power rule: (am)n=amn(a^m)^n = a^{m \cdot n}.
Step 3: Multiply the exponents: 510=505 \cdot 10 = 50.

Thus, the expression simplifies to 8508^{50}.

The correct simplified form of the expression (85)10\left(8^5\right)^{10} is 8508^{50}, which corresponds to choice 2.

Alternative choices:

  • Choice 1: 8158^{15} is incorrect because it misapplies the exponent multiplication.
  • Choice 3: 858^5 is incorrect because it does not apply the power of a power rule.
  • Choice 4: 828^2 is incorrect and unrelated to the operation.

I am confident in the correctness of this solution.
