Simplify
7⁸×7³×7⁴÷7⁹×7⁵

7^11

Step-by-step explanation:

There is a rule for simplifying exponents: n^a + n^b = n^a+b.

The rule applies here too. 7 is the n and the exponents on top are a and b. Following the rule:

Then you continue this formula:

11+4-9+5 = 11

Since the end result is 11 the answer is

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
