To solve for b, first convert b^2/5 to radical form:

root%285%2Cb%29%5E2, and now we have:

36+=+root%285%2Cb%29%5E2

Next, take the square root of both sides:

sqrt%2836%29+=+sqrt%28root%285%2Cb%29%5E2%29

Leaving us with:

6+=+root%285%2Cb%29

Next, multiply each side by itself 5 times:



7776 = b

Remember, because we took the square root of both sides earlier, 6 also became -6, which, when multiplied by itself 5 times, gives us -7776.

Therefore, b = 7776 AND -7776
