Question

If y=m^4=n^3 and y is greater than 1, then mn=?
a. y^1/12
b. y^1/7
c. y^7/12
d. y^7
e. y^12

Answer 1

If \[y=m^4\]what does \(m=\) in terms of \(y\)?
If \[y = n^3\]what does \(n=\) in terms of \(y\)?
Multiply those two expressions together. Remember, you add the exponents when multiplying exponentials with the same base. Do you see the answer?
