What is 125^2/3 in simplest form? and What is \sqrt[5]({-245} ) ^{5} in simplest form?

Natasha_Volkova [10]

${ 125 }^{ \frac { 2 }{ 3 } }\\ \\ ={ \left( { 125 }^{ \frac { 1 }{ 3 } } \right) }^{ 2 }\\ \\ ={ \left( \sqrt [ 3 ]{ 125 } \right) }^{ 2 }\\ \\ ={ 5 }^{ 2 }\\ \\ =25$

This is because:

${ a }^{ \frac { m }{ n } }\\ \\ =\sqrt [ n ]{ { a }^{ m } }$

Remember that:

5 x 5 x 5 = 125

Name the coordinates of point K after its is reflected over the y-axis

Lena [83]

Answer:

(-3,6)

Step-by-step explanation:

When you flip or reflect over the y axis, the x value changes in the original ordered pair, but the y value stays the same

so the original ordered pair is (3,6) so the reflected ordered pair would be (-3,6)
