5 0

Answer:

5.6 *10^7

Step-by-step explanation:

Given

(4.54*10^8)-(3.98*10^8)

Required

Solve

(4.54*10^8)-(3.98*10^8)

Apply distributive law of algebra

(4.54 - 3.98) *10^8

Evaluate the expression in bracket

(0.56) *10^8

Remove bracket

0.56 *10^8

When a number is in standard form: a * 10^n

The value of a must be: 1 \le a \le 10

So, the expression becomes:

5.6 *10^{-1}*10^8

Apply law of indices

5.6 *10^{-1+8}

5.6 *10^7
