83. Use properties of exponents to rewrite each expression with only positive, rational exponents. Then find the numerical value

alexdok [17]

Answer:

$2^{\frac{18}{11}}$

Step-by-step explanation:

The given expression is

$\sqrt[11]{y^2z^4}$

The exponent property $\sqrt[n]{x^ay^b}=x^{a/n}y^{b/n}$

Applying this exponent property, we have

$\sqrt[11]{y^2z^4}\\\\=y^{2/11}z^{4/11}$

Now, the given numeric values are x = 9, y= 8, and z= 16

On substituting these values in the simplified expression, we get

$(2)^{2/11}(16)^{4/11}$

This can be further simplified by writing $16=2^4$

$(2)^{2/11}(2^4)^{4/11}\\\\(2)^{2/11}(2)^{16/11}$

Now, applying the product rule of exponent: $x^a\cdot x^b=x^{a+b}$

$(2)^{2/11+16/11}\\\\=2^{\frac{18}{11}}$

Can somebody Help me please?!

The first one because if you add all the positives you get 4 and then if you add all the negatives you get 7 so then you do 4+(-7)= -3
