Question

combine....

Answer 1

\[10\sqrt{143}+10\sqrt{75}-2\sqrt{192}\]

Answer 2

\[124\sqrt{3}\]?

Answer 3

no

Answer 4

thats interesting as 3 is not a factor of 143....

Answer 5

but you can rewrite the 2nd and 3rd radicals as

\[10\sqrt{75} = 10 \times \sqrt{25}\times \sqrt{3} \]

and

\[-2 \times \sqrt{64} \times \sqrt{3} \]

these 2 radicals need to be simplified... before doing anything else.

Answer 6

hint, 25 and 64 are square numbers so take their square roots

Answer 7

5 and 8
