Pay close attention to the order of operations.

600 000

Practice makes perfect

We want to evaluate the given expression. 0.6 * 10^6 According to the order of operations, the expression with exponent is evaluated first, while multiplication is evaluated last. Knowing this, let's evaluate first the power.

10^6

Rewrite 10^6 as 10 * 10 * 10 * 10 * 10 * 10

10 * 10 * 10 * 10 * 10 * 10

Multiply

1 000 000

Now that we know that 10^6 is 1 000 000, we can substitute 1 000 000 for 10^6 and evaluate the multiplication.

0.6 * 10^6

10^6= 1 000 000

0.6 * 1 000 000

Multiply

600 000

The expression equals 600 000.
