Solution Steps

To multiply powers of the same base, add their exponents. Add 4 and 1 to get 5.

$$5\times 10^{6}-2\times 10^{5}=4$$

Calculate 10 to the power of 6 and get 1000000.

$$5\times 1000000-2\times 10^{5}=4$$

Multiply 5 and 1000000 to get 5000000.

$$5000000-2\times 10^{5}=4$$

Calculate 10 to the power of 5 and get 100000.

$$5000000-2\times 100000=4$$

Multiply 2 and 100000 to get 200000.

$$5000000-200000=4$$

Subtract 200000 from 5000000 to get 4800000.

$$4800000=4$$

Compare 4800000 and 4.
