Solution Steps

Add 1 and 3 to get 4.

$$4+5=3^{2}\text{ and }1+3+5+7=4^{2}$$

Add 4 and 5 to get 9.

$$9=3^{2}\text{ and }1+3+5+7=4^{2}$$

Calculate 3 to the power of 2 and get 9.

$$9=9\text{ and }1+3+5+7=4^{2}$$

Compare 9 and 9.

$$\text{true}\text{ and }1+3+5+7=4^{2}$$

Add 1 and 3 to get 4.

$$\text{true}\text{ and }4+5+7=4^{2}$$

Add 4 and 5 to get 9.

$$\text{true}\text{ and }9+7=4^{2}$$

Add 9 and 7 to get 16.

$$\text{true}\text{ and }16=4^{2}$$

Calculate 4 to the power of 2 and get 16.

$$\text{true}\text{ and }16=16$$

Compare 16 and 16.

$$\text{true}\text{ and }\text{true}$$

The conjunction of \text{true} and \text{true} is \text{true}.

$$\text{true}$$
