Question

Why is the 4/5 in parenthesis when writing 4/5 ^4

4/5 ^4 meaning 4/5 to the power of 4

Answer 1

Explanation:

`$If we typed or wrote $ 4/5^4$ it would be equal to 4/625 because exponent operations are performed before division. If we typed $ 4^4/5$ that is equal to 256/5. Only by putting $ (4/5)^4 $ in parentheses makes the division occur before the exponential operation which is what we want to happen.$`
