Which of the following is equivalent to (5)^7/3
kifflom [539]
<em>The answer is \sqrt[3]{ 5^{7} }</em>

The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>( 5^{7} is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index. 

<em>Here's what a formula would look like:</em> ( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you further! :D

heather has divided $6300 between two invesments, one paying 9%, the other paying 4%. If the return on her investment is $372, h
Ganezh [65]
Assuming that the two investments are  X & Y
X + Y = 6300
X = 6300 - Y                                       (1)

9/100X + 4/100 Y = 372                       (2)
replacing X from (1) into (2)
9/100(6300-Y) + 4/100 Y = 372
567 - 9/100Y +4/100Y = 372
(-9+4)/100Y = 372 - 567
5/100Y = -195
Y = 100*195/5 = 3900
From (1) we can get X
X = 6300 - 3900 = 2400

I hope this is helpful
