If y varies inversely as the square of x, and y = 4/63 when x=3, find y when x=5.

Iwould say that is c

The answer to your question is b’(16,14)

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
