Which of the following is the radical expression of 4 times d to the three eighths power? 4 times the eighth root of d to the third power 4 times the third root of d to the eighth power eighth root of 4 d to the third power <--- my choice third root of 4 d to the eighth power
Like so right? \[4 \times d^\frac{ 3 }{ 8 }\]
yup
ill try to use the equation thing next time on the last question to make it easier on you
4 has no part in the exponent or is in any way connected to d, so it remains outside.
\[4 \times \sqrt[8]{d^3}\] Would be the right answer.
well it's written like this \[4d \frac{ 3 }{ 8 }\]
would the answer still be the one you said?
That's a mixed fraction though..
what do you mean
Are there any parentheses, or is only d raised to the power of 3/8
no parenthesis
Then only d is raised to the 3/8th, and the correct answer is A.
\[4d^\frac{ 3 }{ 8 } = 4\sqrt[8]{d^3}\] \[(4d)^\frac{ 3 }{ 8 } = \sqrt[8]{(4d)^3}\]
k thank you so much and also thanks for the explanation
