use rational exponents to write single radical expression: ^4√8 * ^2√7 I have four ans to choose from: I came up with ^4√392
hi jazil, did you copy the correct prob
let me double check sorry fourth root √8 * second root √7
recheck it now Mark o.
\[\sqrt[4]{8} * \sqrt[2]{7}\]
sqrt4 sqrt8 sqrt2 sqrt7
=2*2sqrt2 (sqrt2 sqrt7) =2*2*2sqrt7 8sqrt7
Mark thanks but what is the ans. look ahead at the format from the equation symbols
sqrt4 sqrt8 sqrt2 sqrt7 =8sqrt7
thats what i can read from the prob
\[\sqrt[4]{8} * \sqrt[2]{7}\] or fourth root √8 * second root √7
we are mult: I have four choices to choose from which are: 1. \[\sqrt[4]{175616}\] 2. \[\sqrt[8]{56}\] 3. \[\sqrt[4]{39}\] 4. \[1/392^{4}\]
just like that or fourth root √8 * second root √7
mark o are you still there
fourth root √8 * second root √7 is this it?
fourth root √8 * second root √7 =((8)^1/2)^1/4* ((7)^1/2)^1/2 (8)^1/8 * (7)^1/4
mark o look at the four choices to choose from for the answer that I posted right before you and tell me which one is it
sory i cant read the answers real good from here, just use the regular typing dont use equations
i dont have equation editor here, cant download them bec of my low memory ofmy hard drive
1. \[\sqrt[4]{175616}\] is this 175616(sqrt4)? 2. \[\sqrt[8]{56}\] 56sqrt[8]] ? 3. \[\sqrt[4]{39}\] 39sqrt4? 4. \[1/392^{4}\] 1/(392^4)?
thats how i read them from here
