What is the value of (4^5+2^8)?

Answer and explanation

Correct answer: 1280

Evaluate the two powers separately: 4^5 = 1024 and 2^8 = 256. Therefore, 4^5 + 2^8 = 1024 + 256 = 1280, so option C is correct. In an exam, calculate each exponent before performing the addition to avoid confusing the bases or exponents.
