Question
analyze the students work below and find the mistake, then correct the work.
josh said that (7^4) is 28 because (7 \times 4 = 28). below explain the error in josh’s thinking, and then write
explanation:
correct answer:
Step1: Recall exponent definition
An exponent \(a^n\) means \(a\) multiplied by itself \(n\) times, not \(a\times n\). So \(7^4 = 7\times7\times7\times7\), not \(7\times4\).
Step2: Calculate \(7^4\)
First, \(7\times7 = 49\). Then, \(49\times7 = 343\). Then, \(343\times7 = 2401\).
