if the expression(2ya)4 is equivalent to 16y8 what is the value of a

To find the value of "a," we can set up an equation based on the information given. Let's start by writing out the expression (2ya)^4 in expanded form:

(2ya)^4 = 16y^8

Now, let's simplify each side of the equation step by step:

On the left side, raising a power to another power means we multiply the exponents. So, we can rewrite (2ya)^4 as (2^4)(y^4)(a^4).

(2^4)(y^4)(a^4) = 16y^8

Since 2^4 equals 16, we can substitute it into the equation:

16(y^4)(a^4) = 16y^8

Now, we can cancel out the 16 on both sides:

(y^4)(a^4) = y^8

To equate the exponents, we can write:

a^4 = y^(8-4)

Simplifying further:

a^4 = y^4

To solve for "a," we need to take the fourth root of both sides:

∛ a^4 = ∛ y^4

This gives us:

a = y

So, the value of "a" is equal to "y" based on the given expression and equation.

a=16
