82. use properties of exponents to rewrite each expression with only positive, rational exponents. then find the numerical value of each expression when x = 9, y= 8, and z= 16. in each case, the expression evaluates to a rational number.
b. 11√y2z4

11yz² and when evaluating we get 22528

Step-by-step explanation:

We have the expression

We know that a square root is a 1/2 exponent, so we're going to multiply the exponents of y and z by 1/2.

Therefore the expression is rewritten as

Now we're going to evaluate this expression for y = 8 and z = 16

Thus, when evaluated the result is 22528

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

1) letter c.

2) 4 square root of 9

hope this
