There are three laws of indices that need to be remembered to simplify any expression with different indices.
a^m*a^n = a^(m+n)
a^m/a^n = a^(m - n)
(a^m)^n = a^(m*n)

There are three laws of indices that need to be remembered to simplify any expression with different indices.
a^m*a^n = a^(m+n)
a^m/a^n = a^(m - n)
(a^m)^n = a^(m*n)
The quadratic formula that gives the roots of a quadratic equation ax^2 + bx + c = 0 is:` x1 = (-b + sqrt(b^2 - 4ac))/(2a)` and `x2 = (-b - sqrt(b^2 - 4ac))/(2a)`
This is quite a simple formula with the roots differentiated only by the sign before the term `sqrt(b^2 - 4ac)` . Solve a few problems using the formula and you will remember it.
