12th Grade Math, (Mathematics for Data and Financial Literacy) Evaluate the numerical expression the quantity 5 to the power of five sixths end quantity over the quantity 5 to the power of one sixth end quantity. square root of 15 square root of 125 cube root of 10 cube root of 25
how you know this rule of powers when you divide the same terms like in your case 5 on different powers this is the formula \[\frac{ x^{a} }{ x^{b} } = x^{(a-b)}\] have you learn about this ?
so to get the correct answer you need use this rule first
There is a lot of formulas like this, what do i do with this?
in ths first step you need calcule \[\frac{ 5 }{ 6 } - \frac{ 1 }{ 6 } = ?\]
how you know to set it up like that?
6/6?
ok
?
i meant 4/6
yes so is right
ok, so what after that then?
but 4/6 you can simplify it
yeah to 2/3
exactly
so how do we get it to square root?
so will get 5 on power of 2/3 about what i ve said that the denominator of a fraction power is the indice of radical so in this case how can you rewrite your result ?
3 square root 5?
meant 10
no 5 will be on power of 2 what is equal 5*5 = ? and the index of radical is 3 what mean cube root
oh so 3 with 25 in the box?
this 3 mean cubroot and yes 5 squared is 25
from these choices what is right ?
so it is d?
perfect do you understand it now sure ?
I have a understanding of it anyway
ok cya
thank you.
