Ok bro now find an expression solver that verifies your solution. I tried Wolfram Alpha, Google, and others, and they all return 128. So either you're wrong, or all people who make these tools professionally are wrong. Not trying to be offensive, but I know where I'm putting my money.
To be clear, the reason you're wrong is because distribution is not part of the brackets step. Brackets are solved before exponents, resulting in 2(8)². Remove the brackets and then it's 2*8²
Yep, all known to give wrong order of operations answers
Well, it's not me, so...
That's right. Welcome to programmers writing Maths apps without checking that they have their Maths right first. BTW, in some cases it's as bad as one of their calculators saying 2+3x4=20! 😂
To be clear, I am correct, because Distribution is part of the Brackets step, as we have already established...
Yes
No, you haven't finished solving the Brackets yet, which you must do before proceeding...
Nope! We have already established that you cannot remove the brackets if you haven't Distributed yet...
So what we actually get is...
2(8)²=(2x8)²=16²
and now that I have removed the Brackets, I can now do the exponent,,,
16²=256
Welcome to you finding the answer to 2x(3+5)² - where the 2 is separate to the brackets, separated from them by the multiply sign - rather than 2(3+5)², which has no multiply sign, and therefore the 2 must be Distributed
Like how the 5 in the first image isn't?
BWAHAHAHAHAHA! And how exactly do you think they got from 5(17) to 85 without distributing?? 🤣 Spoiler alert, this is what they actually did...
5(17)=(5x17)=85
They do that throughout the book, because they think it's so trivial to get from 5(17) to 85, that if you don't know how to do it without writing (5x17) first, then you have deeper problems than just not knowing how to Distribute 😂
