Solve 4.2*10^-2div40^circ=12

$$4.2 \times 10 ^ { - 2 } \div 40 ^ { \circ } = 12$$

Verify

Solution Steps

Multiply both sides of the equation by 40.

$$4.2\times 10^{-2}=480$$

Calculate 10 to the power of -2 and get \frac{1}{100}.

$$4.2\times \frac{1}{100}=480$$

Multiply 4.2 and \frac{1}{100} to get \frac{21}{500}.

$$\frac{21}{500}=480$$

Convert 480 to fraction \frac{240000}{500}.

$$\frac{21}{500}=\frac{240000}{500}$$

Compare \frac{21}{500} and \frac{240000}{500}.

$$\text{false}$$
