Solve n=4*10^5*4.18*10^-3/8.31*400

$$n = \frac{ 4 \times { 10 }^{ 5 } \times 4.18 \times { 10 }^{ -3 } }{ 8.31 \times 400 }$$

Solve for n

$$n=\frac{418}{831}\approx 0.503008424$$

Steps for Solving Linear Equation

To multiply powers of the same base, add their exponents. Add 5 and -3 to get 2.

$$n=\frac{4\times 10^{2}\times 4.18}{8.31\times 400}$$

Cancel out 4 in both numerator and denominator.

$$n=\frac{4.18\times 10^{2}}{8.31\times 100}$$

Calculate 10 to the power of 2 and get 100.

$$n=\frac{4.18\times 100}{8.31\times 100}$$

Multiply 4.18 and 100 to get 418.

$$n=\frac{418}{8.31\times 100}$$

Multiply 8.31 and 100 to get 831.

$$n=\frac{418}{831}$$

Assign n

$$n≔\frac{418}{831}$$
