To solve the expression \( 2^6 \times 2 - 3 \), we need to follow the order of operations:

  1. Calculate \( 2^6 \).
  2. Multiply the result by 2.
  3. Subtract 3 from that product.

Let's break it down:

  1. \( 2^6 = 64 \)
  2. \( 64 \times 2 = 128 \)
  3. \( 128 - 3 = 125 \)

So, the final answer is \( 125 \).

how is it not 21

Let's carefully review the steps again to clarify how we arrived at the answer:

You asked to evaluate the expression \(2^6 \times 2 - 3\).

  1. First, calculate \(2^6\): \[ 2^6 = 64 \]

  2. Next, multiply this result by 2: \[ 64 \times 2 = 128 \]

  3. Finally, subtract 3 from the product: \[ 128 - 3 = 125 \]

Now, regarding your question about why it is not 21, let's analyze this further. There might have been some confusion over how to interpret the expression or perhaps there was a different expression in mind.

If you want to achieve a result of 21, the expression would need to be formatted differently. For instance, if you meant \(2^6 - 3\) instead of \(2^6 \times 2 - 3\), that would yield:

  1. \(2^6 = 64\)
  2. \(64 - 3 = 61\) (still not 21).

If there’s a specific form of the expression that you’re considering or if there's any additional context, please let me know, and I'd be happy to help clarify further!

7x8x2x9

To solve the expression \(7 \times 8 \times 2 \times 9\), you can multiply the numbers step by step:

  1. First, calculate \(7 \times 8\): \[ 7 \times 8 = 56 \]

  2. Then, multiply the result by 2: \[ 56 \times 2 = 112 \]

  3. Finally, multiply that result by 9: \[ 112 \times 9 = 1008 \]

Therefore, \(7 \times 8 \times 2 \times 9 = 1008\).
