Sagot :
Step-by-step explanation:
Given
k = - 2
Now evaluating
√- 72 * - 2
= √ 144
= √ ( 12)²
= 12
Hope it will help you :)❤
The evaluated solution of √-72k for k = -2 is 12.
What is an expression?
Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
What are Arithmetic operations?
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given expression as :
⇒ √-72k
And k= -2
To Evaluate the expression
Now Substitute the value of k= -2 in the expression
⇒ √- 72 × - 2
⇒ √ 144 [√ 144 = 12]
⇒ 12
Hence, the evaluated solution of √-72k for k = -2 is 12.
