How do you solve this? i am having a real hard time on where i need to start, .

c^7/9

Step-by-step explanation:

basically when ever you need to turn a root into an exponent create a fraction where the root number (number on the left in the little dip) is the denominator and the exponent already on the number is the numerator.

so since 9 is on the root, and 7 is the exponent already there, our rational exponent is 7/9.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
