Evaluate each expression

qwelly [4]

Step-by-step explanation:

a = 2
b = 3
c = 5

$\longrightarrow \rm{{\Bigg ( \dfrac{a}{b} \Bigg )}^c} \\ \\ \longrightarrow \rm{{\Bigg ( \dfrac{2}{3} \Bigg )}^5} \\ \\ \qquad \qquad \bigstar \: \boxed{ \bf{ \Bigg ({\frac{x}{y} \Bigg )}^{m} = \frac{ {x}^{m} }{ {y}^{m}} }} \\ \\ \longrightarrow \rm{ \frac{ {(2)}^{5} }{ {(3)}^{5} } } \\ \\ \longrightarrow \bf{ \frac{ 32 }{ 243} }$

Therefore, 32/243 is the answer.

How to solve 1 2/3j=15

ivann1987 [24]

Answer:

j = 9

Step-by-step explanation:

The answer to the question above is solved below.

$1 \frac{2}{3}j = 15$

Convert the mixed numbers to improper fraction following the step: 1×3 = 3 +2 =5 / 3j = 5/3j

$\frac{5}{3}j = 15$

Eliminate the fraction of the equation left hand side by multiplying both sides by 3

$3 \times \frac{5}{3}j = 3 \times 15$

$5j = 45$

Divide both sides by 5

$\frac{5j}{5} = \frac{45}{5}$

$j = 9$

$thus \: if \: 1 \frac{2}{3}j = 15. \: j = 9$
