Question

Is 3 squared times 4 squared equal 12 squared ? Evaluate each side of the equation to explain your answer.

Answer 1

yes

Explanation:

`3^(2)  * 4^(2) =12^(2)`

`3*3=9`

`4*4=16`

`9*16=144`

`12*12=144`

so they both equal 144

Answer 2

Nopes 3²+4²≠12²

Explanation:

12²=144

3²+4²=

9+16=25

25≠144

To make it easier to see exactly WHY 3²+4²≠12² you can spread out the numbers in the equation.

(3·3)+(4·4)≠(12·12)

When solving equations you use PEMDAS (Parenthesis Exponents Multiplication Division Addition Subtraction). You have to solve in THAT ORDER.
