One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I wil

aleksklad [387]

Answer:

Step-by-step explanation:

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years

How to Simplify this

erma4kov [3.2K]

( $u^{ \frac{5}{4} }$ $v^{ \frac{3}{2} }$ ) $^{ \frac{3}{2} }$

( $\sqrt[4]{ u^{5} }$ $\sqrt[]{ v^{3} }$ ) $^{ \frac{3}{2} }$

$\sqrt{( \sqrt[4]{ u^{5} } \sqrt{ v^{3} }) ^{3} }$

$\sqrt{( \sqrt[4]{ u^{5} } \sqrt{ v^{3} }) ^{3} }$

$\sqrt{ \sqrt[4]{( u^{5} v^{6})^{3} } }$

$\sqrt[8]{( u^{5} v^{6})^{3} }$

$\sqrt[8]{ u^{15}v^{18} }$

u $v^{2}$ $\sqrt[8]{ u^{7} v^{2} }$
