Simplify using positive exponents 1. (5^3)^5 2. 7^-2/5^-2 3. -3(5+27)^0 4. 10^-2

Remember, when you distribute exponents, you distribute them to the existing exponent (if there is one) AND the coefficient. Here's the math:

1. 

Distribute  to 5 and 



Multiply the terms accordingly



2. 

Multiply the numerator and denominator by 



Use the Negative Exponent Rule to rearrange the expression



Square the numerator and denominator



Simplify



3. 

If something is multiplied to the power of 0, than it is equal to 0

4. 

For this, we will once again use the Negative Exponents Rule (find the reciprocal and change the negative exponent to its opposite)



Simplify
