Do you know the pythagorean theorem?

awesomemax03:

In a way kindof.

snowflake0531:

So, it's a^2 + b^2 = c^2 Here, we have a and c 5^2 + b^2 =12^2 Can you find 5^2 and 12^2

awesomemax03:

I dont know how to...

snowflake0531:

5^2 is 5 times 5 12^2 is 12 times 12

awesomemax03:

OOOOHHHH

awesomemax03:

so 10 and 24?

snowflake0531:

No what is 5 times 5 What is 12 times 12

snowflake0531:

Multiplication, not addition

awesomemax03:

ok so exponents?

awesomemax03:

so 25 and 144

snowflake0531:

Okay so 25+ b^2 = 144 b^2 =....

awesomemax03:

59.5?

snowflake0531:

No What is 144-25

awesomemax03:

119

snowflake0531:
