when you have a fraction as an exponent, (z'th root of x)^y is x^y/z. cube each side to solve

you should leave it for the master mathematician OP to answer.

How do inter-species cybrids illustrate the tight co-evolution of the mitochondrial genome and nuclear DNA encoded factors? How do copepod inter-population cybrids illustrate the time frame of mitochondrial-nuclear co-evolution?

you tell me.


8^(1/3) + 8^(1/3) = 4

so you're saying cube each side will remove the 1/3 fractional power to get:

8 + 8 = 4^3

is that what you're saying?

answer is 12/7.....

(7x-2)^(1/3) + (7x+5)^(1/3) = 3

cube each

7x-2 + 7x+5 = 27
14x = 24
x = 12/7
