value of |7|-|-6|+|-cubicroot-64|
i got 25 after doing whole thing but real answer be 5, i not get how to get that.
(-64)^(1/3) = -4
7 - 6 + 4 = 5
cubicroot( -64 ) = -4
| 7 | = 7
| -6 | = 6
|cubicroot ( -64 )| = 4
| 7 | - | -6 | + | -cubicroot ( -64 ) | = 7 - 6 + 4 = 1 + 4 = 5
thanks:)
^ to both of you guys :)
@ Anonymous if you not busy can u please look at my other questions below?
To find the value of the expression |7| - |-6| + |-∛(-64)|, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right), commonly known as PEMDAS.
First, let's simplify the expression step by step:
1. |7| - |-6| + |-∛(-64)|
Since the absolute value of a positive number is itself, the first two terms become:
|7| = 7
|-6| = 6
Now the expression is:
7 - 6 + |-∛(-64)|
To simplify the last term, let's calculate the cube root of -64:
∛(-64) = -4
Note: In mathematics, the cube root of a negative number yields a negative result.
Now the expression becomes:
7 - 6 + |-4|
Since the absolute value of -4 is 4, the expression becomes:
7 - 6 + 4
Now we can perform the remaining addition and subtraction, from left to right:
7 - 6 + 4 = 1 + 4 = 5
Therefore, the correct value of the expression is 5, not 25 as you have mentioned.
