Solve -2*10^-18lceil3/16rceil

$$-2 \times { 10 }^{ -18 } \lceil \frac{ 3 }{ 16 } \rceil$$

Evaluate

$$-\frac{1}{500000000000000000}=-2 \cdot 10^{-18}$$

Solution Steps

Calculate 10 to the power of -18 and get \frac{1}{1000000000000000000}.

$$-2\times \frac{1}{1000000000000000000}\lceil \frac{3}{16}\rceil$$

Multiply -2 and \frac{1}{1000000000000000000} to get -\frac{1}{500000000000000000}.

$$-\frac{1}{500000000000000000}\lceil \frac{3}{16}\rceil$$

The ceiling of a real number a is the smallest integer number greater than or equal to a. The ceiling of 0+\frac{3}{16} is 1.

$$-\frac{1}{500000000000000000}$$

Factor

$$-\frac{1}{500000000000000000} = -2 \times 10^{-18}$$
