just a little indices query... *please wait whilst i write it as an equation* Thanks =)
express \[16^{3}\] as \[2^{?}\]
or express \[125^{4/3}\] as \[5^{?}\]
first one is (2^4)=16 so replace 16 with 2^4-->(2^4)^3--->2^12=4096, which is the the same value as 16^3
for the second one, i will only give you a hint: 125=5^3
sly hint... ahaha =)
how about expressing\[1/27\] as \[3^{?}\] ?
So, yes that was sly hint. Whaddya think? Try a guess! ;p
125 \[125^{4/3} = (5^{3})^{4/3} = 5^{4}\]
hmm, do you know that, \[\large x^{-m} = \frac {1}{x^m} \]
1/27 = 3^(-3)
thaanksss =)
Are you getting how we do this, the concept? Try to understand what LagrangeSon and Zeerak did up there^^.
yeahh thanks but i got an advanced one that im trying now... its hardd :/
Hmm, post that one too just in case you want to verify your answer :)
work out\[(1/64)^{-1/2}\]
It is 8.
howww?? :S
\[1/64^{-1/2} = 64^{1/2} = 8^{2*1/2} = 8\]
ahh i seee! thanks =)
