$$3 - \sqrt { 49 } + 2 ( 3 + 4 ^ { 2 } ) = 172$$

Verify

Solution Steps

Calculate the square root of 49 and get 7.

$$3-7+2\left(3+4^{2}\right)=172$$

Subtract 7 from 3 to get -4.

$$-4+2\left(3+4^{2}\right)=172$$

Calculate 4 to the power of 2 and get 16.

$$-4+2\left(3+16\right)=172$$

Add 3 and 16 to get 19.

$$-4+2\times 19=172$$

Multiply 2 and 19 to get 38.

$$-4+38=172$$

Add -4 and 38 to get 34.

$$34=172$$

Compare 34 and 172.

$$\text{false}$$
