Question

A^3=8, a^9= сколько будет

Answer 1

$a^3=8\\\\a^9=a^{3\cdot 3}=(a^3)^3=8^3=512$

Answer 2

a³=8

a=2

a^9=2^9=512

.............

Answer 3

To find the value of a^9 when a^3 = 8, we can use the information provided and some basic algebraic manipulation. Let's proceed step-by-step:

1. Given A^3 = 8
2. We want to find a^9

To get from A^3 to a^9, we need to understand the relationship between A and a. It seems that there might have been a typo in your question, and A and a are being used interchangeably. We'll assume that A and a represent the same variable.

Now, let's proceed with the solution:

We have A^3 = 8

To find A, we take the cube root of both sides:

A = (8)^(1/3)

Now, we can use this value of A to find a^9:

a^9 = (A^3)^3

Substitute the value of A:

a^9 = (8^(1/3))^3

Now, when you raise a number to an exponent and then raise that result to another exponent, you simply multiply the exponents:

a^9 = 8^(1/3 * 3)

a^9 = 8^1

a^9 = 8

So, when a^3 = 8, then a^9 = 8.
