In the following exercises,simplify
$(a) {(625 n^{\frac{8}{3}})}^{\frac{3}{4}} (b) {(9 x^{\frac{2}{5}} y^{\frac{3}{5}})}^{\frac{5}{2}}$

Short Answer

Expert verified

$(a) 125 u^{2} (b) 243 x y^{\frac{3}{2}}$

Step by step solution

Part (a) Step 1.Given information

Consider the given expression ${(625 n^{\frac{8}{3}})}^{\frac{3}{4}}$

To simplify the expression,by used power property that is ${(a^{m})}^{n} = a^{m . n}$ .

Part (a) Step 2. Simplify the expression

${(625 n^{\frac{8}{3}})}^{\frac{3}{4}} = {(625)}^{\frac{3}{4}} . {(n^{\frac{8}{3}})}^{\frac{3}{4} [\sin c e; {(a b)}^{m} = {(a)}^{m} . {(b)}^{m}]} = {(5^{4})}^{\frac{3}{4}} . {(n^{\frac{8}{3}})}^{\frac{3}{4} [\sin c e; 5^{4} = 625]} = {(5)}^{4 . \frac{3}{4}} {(n)}^{\frac{3}{4} \frac{8}{3} [\sin c e; {(a^{m})}^{n} = a^{m n}]} = {(5)}^{\frac{12}{4}} . {(u)}^{\frac{24}{12}} [M u l t i p l a y t h e e x p o n e n t] = {(5)}^{3} . {(u)}^{2} [D i v i d e t h e e x p o n e n t] = 125 u^{2} [S i m p l i f y] T h e r e f o r e, t h e a n s w e r i s 125 u^{2}$

Part (b) Step 1.Given information

Consider the given expression ${(9 x^{\frac{2}{5}} y^{\frac{3}{5}})}^{\frac{5}{2}}$

To simplify the expression,by used power property that is ${(a^{m})}^{n} = (a^{m n})$ .

Part (b) Step 2.Simplify the expression

${(9 x^{\frac{2}{5}} y^{\frac{3}{5}})}^{\frac{5}{2}} = (9^{\frac{5}{2}}) . {(x^{\frac{2}{5}})}^{\frac{5}{2}} . {(y^{\frac{3}{5}})}^{\frac{5}{2}} [S i n c e; {(a b)}^{m} = {(a)}^{m} . {(b)}^{m]} = {(3^{2})}^{\frac{5}{2}} . {(x^{\frac{2}{5}})}^{\frac{5}{2}} . {(y^{\frac{3}{5}})}^{\frac{5}{2} [S i n c e; 2^{2} = 4]} = {(3)}^{2 . \frac{5}{2}} {(x)}^{\frac{5}{2} . \frac{2}{5}} . {(y)}^{\frac{5}{2} . \frac{3}{5} [S i n c e {(a^{m})}^{n} = a^{m . n}]} = {(3)}^{\frac{10}{2}} . {(x)}^{\frac{10}{10}} . {(y)}^{\frac{15}{10}} [M u l t i p l a y t h e e x p o n e n t] = 3^{5} . x . y^{\frac{3}{2}} [D i v i d e t h e e x p o n e n t] = 243 x y^{\frac{3}{2}} [s i m p l i f y] T h e r e f o r e, t h e a n s w e r i s 243 x y^{\frac{3}{2}} .$
