Question

12 + x to the power of 4 - 6 when x = 8

Answer 1

To solve the expression 12 + x to the power of 4 - 6 when x = 8, you substitute 8 for x, calculate the exponent, and then perform the addition and subtraction, resulting in the final answer of 4102.

Step-by-step explanation:

The student's question asks to evaluate an algebraic expression when a particular value is substituted for the variable x. To address the equation 12 + x to the power of 4 - 6 when x = 8, we substitute 8 for x and then follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

• First, substitute x with 8: 12 + 84 - 6.
• Then, calculate the exponent: 12 + 4096 - 6.
• Finally, perform the addition and subtraction: 4102.

The solution to the equation given x = 8 is 4102.

Answer 2

value of
`12+x^4-6` at x=8 is
`5002` .

Step-by-step explanation:

here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or ,
`12+x^4-6` where x=8 . Let's find out:

⇒
`12+x^4-6`

Putting x =8 :

⇒
`12+8^4-6`

Splitting 8 to power 4 into 8 to power 2 ( 2 times )

⇒
`12+8^2(8^2)-6`

⇒
`12+64(64)-6`

⇒
`12+4096-6`

⇒
`4096+6`

⇒
`5002`

Therefore , value of
`12+x^4-6` at x=8 is
`5002` .
