Set it up

100

What is the next step ?

6^{2 +}8^{2 =} C ² 

^{36 + 64 = C2}

Add together 36 + 64

and square root 100

200

What is the next step 

4^{2 +} b^{2 =} 25²

You need to multiply 4 x 4 and 25 x 25

300

What is the next step 

5^{2 +} b^{2 =} 13²

25 ⁺ b^{2 =} 169

Subtract 25 from both sides

400

What is the next step and what is the answer?

25 + b^{2 =} 169

-25          -25

----------------

 b^{2 = 144}

square root both sides 

the answer is 12
