Solve 5*140^2div4tan(36)

$$5 \times { 140 }^{ 2 } \div 4 \tan ( 36 )$$

Evaluate

$$17800.2919361313396$$

Solution Steps

Evaluate trigonometric functions in the problem

$$5 \cdot {(140)} ^ {2} / 4 \cdot 0.7265425280053608$$

Calculate 140 to the power of 2 and get 19600.

$$\frac{5\times 19600}{4}\times 0.7265425280053608$$

Multiply 5 and 19600 to get 98000.

$$\frac{98000}{4}\times 0.7265425280053608$$

Divide 98000 by 4 to get 24500.

$$24500\times 0.7265425280053608$$

Multiply 24500 and 0.7265425280053608 to get 17800.2919361313396.

$$17800.2919361313396$$

Factor

$$\frac{100908684445189 \cdot 3 ^ {2} \cdot 7 ^ {2}}{2 ^ {11} \cdot 5 ^ {13}} = 17800\frac{729840328352}{2500000000000} = 17800.29193613134$$
