In the next video you are shown how to work with rational (fractional) indices using the rule.

how did you get from : 1(9/16) to 25/16

1 = 16/16, so 1 whole and a further 9/16 gives 25/16.

CAN YOU BE MORE CLEAR IN THAT PART PLEAS

Hi, for example 8, how did you get x^18?? Thanks

The square root of x^36 is x^18. For square rooting you halve the power.

((16×1)+ 9)/16 16×1=16 16+9=25 (16+9)/16 =25/16

16×1=16

16+9=25

(16+9)/16 =25/16
