This question never got answered and I would appreciate it if someone could take a look at it.
Simplify
12(6^/(5^-4^) + 7
My thoughts
12(36/(5^-4^) + 7
12(36/9) + 7
12 (4) + 7
12 * 11
132

Your notation is weird.
5^-4 = 1/5^4 = 1/625
No idea what 5^-4^ means, or 6^/...

^ means squared and is the way we have been taught to show it.
So the 1st part of your question reads
5 squared - 4 squared
2nd part is
6 squared divided by
Thank you
Hiya,
i read through this and 132 isn't the answer. you need to do B.I.D.M.A.S
so...
simplify
12(6^/ (5^-4^))+7
12(6^/ (25-16))+7
12(6^/ (9))+7
12(36/ (9))+7
12(36/9)+7
12(4)+7
(12 x 4)+7
(48)+7
48+7=55
ANSWER=55
Normally, the ^ needs an exponent after it. So, I read it now as
12(6^2/(5^2-4^2)) + 7
12(36/(25-16))+7
12(36/9)+7
12(4)+7
48+7
55
You were ok until the last step. Unless otherwise indicated, multiplication is done before addition.
Ah. I see what went wrong; your unbalanced parentheses made me guess wrong. You evidently meant
12(6^2/(5^2-4^2) + 7)
In that case, your answer is correct.
But your penultimate line
12(4) + 7
clearly means 12*4 + 7 = 48+7
Your answer requires 12(4+7)
actually you have placed the brackets in wrong.
12(4)+7
BECOMES: 12*4+7
You said that you place the brackets like this: 12* (4+7)
However,
B.I.D.M.A.S: (Multiply comes before add)
so.. the brackets actually go like this: (12*4)+7
giving you 55
(if you don't belive me go get a scientific calculator and type it in.)
To simplify the expression 12(6^/(5^-4^) + 7), start by evaluating the exponents. The notation 5^-4^ is unclear, but assuming it means "5 raised to the power of -4", we can rewrite it as 1/5^4.
So, the expression becomes 12(6^(1/5^4) + 7).
Next, evaluate the exponent 1/5^4, which is 1/(5 raised to the power of 4).
5^4 is equal to 625, so 1/5^4 is equal to 1/625.
The expression now simplifies further to 12(6^(1/625) + 7).
At this point, it's unclear what 6^(1/625) means since there is a missing term or an operation sign after the caret (^). If we assume it represents a square root, then √6^(1/625) can be computed.
To compute this, take the 625th root of 6, which is approximately equal to 1.014.
Now we have 12(1.014 + 7).
Simplifying that, we get 12(8.014).
Multiply 12 by 8.014, which equals 96.168.
So, the simplified expression is approximately equal to 96.168.
