Answer:


5.6 *10^7

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
