2x^2 square root of 13

Reptile [31]3 years ago

5 0

Answer:

2x^2(root13)

Step-by-step explanation:

52 factors into 13 (prime number) and 4 (perfect sqare)

this means we can take the root of 4 and bring it outside to become a 2

x^4 is a perfect square and is x^2 squared.

so then we have a 2 and x^2 on the outside and a 13 on the inside.

Chris tried to rewrite the expression \left( 4^{-2} \cdot 4^{-3} \right)^{3}(4

crimeas [40]

We have been given an expression $\left( 4^{-2} \cdot 4^{-3} \right)^{3}$ . We have been given steps how Chris tried to solve the given expression. We are asked to choose the correct option about Chris's work.

Let us simplify our given expression.

Using exponent property, $a^m\cdot a^n=a^{m+n}$ , we cab rewrite our given expression as:

$\left( 4^{-2+(-3)} \right)^{3}$

$\left( 4^{-5} \right)^{3}$

Now we will use exponent property $(a^m)^n=a^{m\cdot n}$ to further simplify our expression.

$\left( 4^{-5} \right)^{3}= 4^{-5\cdot 3}$

$\left( 4^{-5} \right)^{3}= 4^{-15}$

Therefore, Chris made mistake in step 2.

Plz help me thx if u do

ivolga24 [154]

Answer:

So, C, and D.. can easily be marked incorrect. This is because in the question it asks, "Atleast 16" This leaves us with answer choice A and B. Answer choice (A), is a closed circle, while answer choice (B) is an open circle.

Closed circles include the number at the end point (less than/greater than/equal to), and open circles do not (less than greater than).

answer choice A. Closed circle, shifting to the right.
