Solution Steps

Evaluate trigonometric functions in the problem

$$4500 \cdot 12336 {(10)} ^ {-4} \cdot -0.5131463061982381$$

Multiply 4500 and 12336 to get 55512000.

$$55512000\times 10^{-4}\left(-0.5131463061982381\right)$$

Calculate 10 to the power of -4 and get \frac{1}{10000}.

$$55512000\times \frac{1}{10000}\left(-0.5131463061982381\right)$$

Multiply 55512000 and \frac{1}{10000} to get \frac{27756}{5}.

$$\frac{27756}{5}\left(-0.5131463061982381\right)$$

Multiply \frac{27756}{5} and -0.5131463061982381 to get -\frac{35607222187095741759}{12500000000000000}.

$$-\frac{35607222187095741759}{12500000000000000}$$
