Pay close attention to the order of operations.

6200

Practice makes perfect

We want to evaluate the given expression. 6.2 * 10^3According 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.

10^3

Rewrite 10^3 as 10 * 10 * 10

10 * 10 * 10

Multiply

1000

Now that we know that 10^3 is 1000, we can substitute 1000 for 10^3 and evaluate the multiplication.

6.2 * 10^3

10^3= 1000

6.2 * 1000

Multiply

6200

The expression equals 6200.
