What is the value of (2^5+2^4)?
Advertisement
Answer and explanation
Correct answer: 48
Evaluate the powers first: \(2^5=32\) and \(2^4=16\). Therefore, \(2^5+2^4=32+16=48\), so 48 is correct. The value 32 represents only \(2^5\); \(2^4\) still has to be added. Exam tip: In expressions with exponents, evaluate the powers before performing addition or subtraction.
