Which expression is equivalent to the expression shown

C)

Step-by-step explanation:

The given expression is

Here we have to use exponent rule of quotient.

Rule:

If we have to the same base, we can use the formula.

So we rewrite 4^10 / 4^5 using this rule.

So,

Therefore, the answer is C)

45

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
