Solve 1.28*10^-9=6.63*10^-34*3*10^8/x

$$1.28 \times 10 ^ { - 9 } = \frac { 6.63 \times 10 ^ { - 34 } \cdot 3 \times 10 ^ { 8 } } { x }$$

Solve for x

$$x=0.000000000000000155390625$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.

$$1.28\times 10^{-9}x=6.63\times 10^{-34}\times 3\times 10^{8}$$

To multiply powers of the same base, add their exponents. Add -34 and 8 to get -26.

$$1.28\times 10^{-9}x=6.63\times 10^{-26}\times 3$$

Calculate 10 to the power of -9 and get \frac{1}{1000000000}.

$$1.28\times \frac{1}{1000000000}x=6.63\times 10^{-26}\times 3$$

Multiply 1.28 and \frac{1}{1000000000} to get \frac{1}{781250000}.

$$\frac{1}{781250000}x=6.63\times 10^{-26}\times 3$$

Calculate 10 to the power of -26 and get \frac{1}{100000000000000000000000000}.

$$\frac{1}{781250000}x=6.63\times \frac{1}{100000000000000000000000000}\times 3$$

Multiply 6.63 and \frac{1}{100000000000000000000000000} to get \frac{663}{10000000000000000000000000000}.

$$\frac{1}{781250000}x=\frac{663}{10000000000000000000000000000}\times 3$$

Multiply \frac{663}{10000000000000000000000000000} and 3 to get \frac{1989}{10000000000000000000000000000}.

$$\frac{1}{781250000}x=\frac{1989}{10000000000000000000000000000}$$

Multiply both sides by 781250000, the reciprocal of \frac{1}{781250000}.

$$x=\frac{1989}{10000000000000000000000000000}\times 781250000$$

Multiply \frac{1989}{10000000000000000000000000000} and 781250000 to get \frac{1989}{12800000000000000000}.

$$x=\frac{1989}{12800000000000000000}$$
