Powers exercises for 2nd year of ESO (Spanish secondary education) solved step by step: learn how to solve and simplify mathematical operations with powers, integers, and properties of powers with explained solutions.
Could you solve 3^7 · 9^2 / 27^3 mentally? It seems difficult because of the 27 cubed, but in this #Shorts I'll show you that it's child's play if you know the properties of powers!
In this algebra exercise, the trick is to bring all the expressions to a common base: base 3 (9 = 3^2 and 27 = 3^3). By applying powers of powers and the laws of exponents for multiplication and division, the result appears in seconds.
Put your math skills to the test!
