Question

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

Answer 1

Answer:

yes

Step-by-step 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

Answer:

Nopes 3²+4²≠12²

Step-by-step 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.
