Question

Need help:(.... Simplify (b^5)^2

Answer 1

For this case we must indicate an expression equivalent to:

$(b ^ 5) ^ 2$

We have that by definition of properties of powers that is fulfilled:

$(a ^ n) ^ m = a ^ {n * m}$

Now, we can rewrite the given expression as:

$(b ^ 5) ^ 2 = b ^ {5 * 2} = b ^ {10}$

ANswer:

$b^{10}$

Option A

Answer 2

b^10 would be the correct answer :)
