Question

(5x^(2/3))(4x^(1/4)) how do you multiply this

Answer 1

20x^ (11/12)

Answer 2

multiply the coefficients 5 and 4 to get 20, this is the final coefficient


now add the exponents to get 2/3 + 1/4 = (2/3)*(4/4) + (1/4)*(3/3) = 8/12+3/12 =11/12


So the final exponent is 11/12


So the answer is 20x^(11/12)

Answer 3

but what do you do with the exponenta

Answer 4

you add them

Answer 5

woahh i dont get what you did. do you need common denominator?

Answer 6

sry, it's a bit jumbled


2/3 + 1/4


(2/3)*(4/4) + 1/4 ... Multiply top and bottom of the first fraction by 4


8/12 + 1/4


8/12+(1/4)(3/3) ... Multiply top and bottom of the second fraction by 3


8/12 + 3/12


(8+3)/12


11/12


So 2/3 + 1/4 = 11/12

Answer 7

yeah, in order to add the fractions, you need to get all the denominators equal to the LCD (in this case 12)
