The expression would be d + 3.

You're raising $3 in every sweaters cost so d is the cost of the sweater and you add 3 to raise $3 in the price.

Hope this helps :)

Simplify: squareroot 64r^8 8r2 8r4 32r2 32r4

Sav [38]

Answer:

8r^4

Step-by-step explanation:

√(64r^8) = √((8r^4)^2) = 8r^4

_____

You can make use of either or both of these rules of exponents:

(a^b)^c = a^(b·c) . . . . . used above

$\sqrt[n]{a}=a^{\frac{1}{n}}$

Using the second rule, you can write the expression as ...

$\sqrt{64r^8}=\sqrt{64}\cdot r^{8\cdot\frac{1}{2}}=8r^4$
