What’s 90 divided by [10 +(3 to the second power -4)]= ?
in more normal notation,
90/(10 + 3^2 - 4)
= 90/(10+9-4)
= 90/15
= 6
= 56
in more normal notation,
90/(10 + 3^2 - 4)
= 90/(10+9-4)
= 90/15😁= 6
If I read that right it is 90/[10 + (3^2 -4)] = 90/[10 + (9-4)] = 90/[10 + 5] = 90/15 = 6
Check that.

To solve this expression, we need to follow the order of operations, also known as PEMDAS.
P - Parentheses (simplify anything inside parentheses)
E - Exponents (perform any calculations involving exponents)
MD - Multiplication and Division (perform any multiplication or division from left to right)
AS - Addition and Subtraction (perform any addition or subtraction from left to right)
Let's break down the expression step by step:
First, let's simplify the term inside the parentheses:
3 to the second power = 3^2 = 9
9 - 4 = 5
Now we have:
10 + 5
Next, let's add the numbers inside the parentheses:
10 + 5 = 15
Finally, divide 90 by 15:
90 ÷ 15 = 6
So, the final answer is 6.
