Answer:

Step-by-step explanation:

Exponent properties state that when two like bases are being divided, the exponents can be subtracted. So the first step in simplifying is to subtract the two exponents, 4-2=2. This leaves the fraction as $\frac{7^{2} }{7^{0} }$ , since anything to the power of 0 is just 1, the simplified expression is $7^{2}$ . Then, because they are both constants, 7 can just be squared. This equals 49.

Naily [24]

Answer:

The Total Weight of candy is $5\frac{8}{15} \ pounds$ .

Step-by-step explanation:

Given:

Amount of Jelly beans Susie have = $3\frac{1}{5}$ pounds

$3\frac{1}{5}$ can be rewritten as $\frac{16}{5}$

Also Given;

Julie has amount of licorice = $2\frac{1}{3}$ pounds

$2\frac{1}{3}$ can be Rewritten as $\frac{7}{3}$

Now Julie wants to combined her bag of licorice with Susie's jellybeans.

Hence the Total weight of candy will be the sum of Amount of Jelly beans and amount of licorice.

Total weight of candy = $\frac{16}{5} + \frac{7}{3}$

Now making the Denominator common we get;

Total weight of candy = $\frac{16\times3}{5\times 3} + \frac{7\times5}{3\times5}= \frac{48}{15} + \frac{35}{15}=\frac{48+35}{15}= \frac{83}{15} \ pounds$
