This blog notes down all key concepts and properties to remember to be able to infer and use for **GMAT exponents related problems**. Many GMAT Data Sufficiency problems will need the know-how of the rules so we can infer if sufficient information is available or not. **These exponents questions** should be straightforward once we know all the properties.

## GMAT **Exponents **Properties

**Square Root:**The solution of the square root of a number is always positive. e.g.**sqrt(25)****is always 5 and not +/- 5**. This is in contrast to the solution of x^2 = 25.**The solution for x is +/- 5.****Product Rule:**When you multiply**two numbers with same and different/same exponent.**The product of the numbers will be output with the same base and**the exponent will be the sum of the two.**- (2^a)*(2^b) = 2^(a+b)

**Power Rule:**When you raise a base to a power a. Then further raise it to a power b. The output can be written as a base**(x^a)^b = x^(a*b)**

These are broadly the 3 points used within GMAT Exponents.
