Solve 7*7+6/2+22*7*3*5^-3

$$7 \times 7 + 6 / 2 + 22 \cdot 7 \times 3 \cdot 5 ^ { - 3 }$$

Evaluate

$$\frac{6962}{125}=55.696$$

Solution Steps

Do the multiplications.

$$49+\frac{6}{2}+154\times 3\times 5^{-3}$$

Divide 6 by 2 to get 3.

$$49+3+154\times 3\times 5^{-3}$$

Add 49 and 3 to get 52.

$$52+154\times 3\times 5^{-3}$$

Multiply 154 and 3 to get 462.

$$52+462\times 5^{-3}$$

Calculate 5 to the power of -3 and get \frac{1}{125}.

$$52+462\times \frac{1}{125}$$

Multiply 462 and \frac{1}{125} to get \frac{462}{125}.

$$52+\frac{462}{125}$$

Add 52 and \frac{462}{125} to get \frac{6962}{125}.

$$\frac{6962}{125}$$

Factor

$$\frac{2 \cdot 59 ^ {2}}{5 ^ {3}} = 55\frac{87}{125} = 55.696$$
