Question

what is 2^6x2-3?
21
125
-128
24

Answer 1

how is it not 21

Answer 2

7x8x2x9

Answer 3

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 \( 125 \).

Answer 4

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!

Answer 5

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