What is the value of (5^3+2^5)?
Answer and explanation
Correct answer: 157
First evaluate the powers: \(5^3=5\times5\times5=125\) and \(2^5=2\times2\times2\times2\times2=32\). Therefore, \(5^3+2^5=125+32=157\). Option 147 results from an incorrect evaluation of a power or the addition. Exam tip: In expressions with exponents, evaluate each power before performing addition or subtraction.
