By what number should we multiply 3³ so that the product may be equal to 3⁷

Solution:

Multiply 3³ by x so that the product is equal to 3⁷

From the question

3³ × x = 3⁷

We can write it as

x = 3⁷ ÷ 3³

We know that

a^m ÷ aⁿ = a^m-n

x = 3^7-3

x = 3⁴

So we get

x = 81

Therefore, 3³ should be multiplied with 81.
