Solve (9·3)÷8^0: Zero Exponent Division Problem

Question

9380=? \frac{9\cdot3}{8^0}=\text{?}

Video Solution

Solution Steps

00:00 Simply
00:03 According to power laws, any number raised to power 0 equals 1
00:06 As long as the number is not 0
00:09 We will use this formula in our exercise
00:14 A number divided by 1 is the number itself
00:20 We'll break down 9 as 3 squared
00:24 When multiplying powers with equal bases
00:27 The power of the result equals the sum of the powers
00:33 We'll use this formula in our exercise, we'll sum the powers
00:37 And this is the solution to the question

Step-by-Step Solution

We use the formula:

a0=1 a^0=1

9×380=9×31=9×3 \frac{9\times3}{8^0}=\frac{9\times3}{1}=9\times3

We know that:

9=32 9=3^2

Therefore, we obtain:

32×3=32×31 3^2\times3=3^2\times3^1

We use the formula:

am×an=am+n a^m\times a^n=a^{m+n}

32×31=32+1=33 3^2\times3^1=3^{2+1}=3^3

Answer

33 3^3
