**Hi class, I'm Maite :)**

Today we haven't done any special, we have corrected the exercises of last week (56, 57, 60 and 64).

In the exercise 64

**Mario**has**explained us that:**
a)

**(5 2 x 25 2)3 = 5 6 x 25 6 = 56 x (52)6 = 5 6 x 5****12****=****5****18**
* We can't do a multiplication of two powers if they don't have the same base, but in this case 25 is a multiple of 5, so it can be simplyfied as

**52.**
So the multiplication remains as :

**5 6 x (5 2)****6****We don't have finished the exercise because we have angered Mario with our behavior.**

**Next lesson we should behave better !!!**

Red: the exponent

Thank you for your entry Maite! :D

ReplyDeleteI'm really willing to teach you to upload entries involving mathematic formulas and expressions :)

This lyrics extract from Smashing Pumpkins' 1996 hit song "Tonight tonight" describes what some people of our class feel... :P

"AND YOU KNOW YOU'RE NEVER SURE

BUT YOUR SURE YOU COULD BE RIGHT"
