Answer:

7.2 × 10⁷ = 72,000,000

7.2 × 10⁴ = 72,000

6.4 × 10⁷ = 64,000,000

6.4 × 10⁴ = 64,000

*image* = 64,000

Explanation:

Solve the equation.

( 8 × 10² ) ( 3.2 × 10⁵ )

4 × 10³

Step 1: Solve the parenthesis

( 8 × 10² ) ( 3.2 × 10⁵ )

↓ ↓

= (800) = (320,000)

Step 2: Solve for the denominator

4 × 10³

= 4,000

Step 3: Plug in the answers & solve

1. ( 800 ) ( 320,000 )

2. 4,000

1. 800 × 320,000

= 256,000,000

2. 256,000,000

4,000

256,000,000 ÷ 4,000

= 64,000

I hope this was helpful! (✿◠‿◠)

Have a blessed day!
