Terry was asked to evaluate 2^7. He multiplied 2 times 7 and got the answer 14. Explain why Terry's answer is incorrect. Then, evaluate 2^7.

Answer 1

Terry's answer is incorrect because to evaluate 2^7, you need to multiply 2 by itself 7 times, not multiply 2 by 7.

Evaluating 2^7:
2^7 = 2 x 2 x 2 x 2 x 2 x 2 x 2 = 128

So, the correct answer is 128.
