Answer:
(2xy)³
Step-by-step explanation:
According to the Power Rule of Exponents:
We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.
8 is a perfect cube of 2: ⇒ 2 × 2 × 2 = 2³ = 8
The cube of x is x³: ⇒ x × x × x = x³
The cube of y is y³ ⇒ y × y × y = y³
Hence, we can take the least common factors, (2xy) and raise them to the third power:
(2xy)³ = 2³x³y³ = 8x³y³
Therefore, the correct answer is: (2xy)³
value of at x=8 is
.
<u>Step-by-step explanation:</u>
here we need to evaluate 12 + x to the power of 4 - 6 when x = 8 or , where x=8 . Let's find out:
⇒
Putting x =8 :
⇒
Splitting 8 to power 4 into 8 to power 2 ( 2 times )
⇒
⇒
⇒
⇒
⇒
Therefore , value of at x=8 is
.
