Choice B is the correct answer. Substitute and calculate.

1. Substitute: $f(4) = 10(2)^4$.
2. Exponentiate: $2^4 = 16$.
3. Multiply: $10 \times 16 = 160$.

💡 Strategic Tip:$2^4$ is $2 \times 2 \times 2 \times 2 = 16$. Don't do $10 \times 2$ first.

Choice A is incorrect because it calculates $10 \times 8$ ($2^3$). Choice C is incorrect because it calculates $10 \times 2$. Choice D is incorrect because it calculates $(10 \times 2)^4$ or $10^4$.
