(x^3)(y^2)(x^5)(z^2)

Use the Product Theorem for Exponenets, which says if m and n are real numbers and x does not equal 0, x^m * x^n = x^(m+n).

x^3 = 27

Take the cube root of each side.

x = 3

'; explain[9] = '#10

3^x = 81

Take the xth root of each side.

3 = xRT(81)

The 4th root of 81 is equal to 3.

x = 4
