Ipatiy [6.2K]

if in total Kasey has 8 packaged of gelatin and it takes 1 1/3 for each mold which equals 6 servings than you could work it out as

8 divided by 1 1/3=6.015 since its not a whole number than you'd want to go down to just 6 resulting in Kasey creating 6 molds

6 molds times 6 servings= 36 servings

Which expressions are equivalent to 7^{-2}\cdot 7^67
AleksandrR [38]

Answer:

{7}^{ - 2}   \cdot \:  {7}^{6}  =  {7}^{ 4}

Step-by-step explanation:

The given expresion is;

{7}^{ - 2}  \cdot {7}^{6}

We apply the product rule of indices;

{a}^{m}   \cdot \:  {a}^{n}  =  {a}^{m + n}

We apply this property to our expression to get:

{7}^{ - 2}   \cdot \:  {7}^{6}  =  {7}^{ - 2 + 6}

Simplify the exponent on the right;

{7}^{ - 2}   \cdot \:  {7}^{6}  =  {7}^{ 4}

We can't see the options, but I hope this helps!
