Question

HELP ME PLEASE!!!!

Answer 1

`8=4\cdot2\\72=36\cdot2\\\\17\sqrt8+9√(72)=17√(4\cdot2)+9√(36\cdot2)=17\cdot\sqrt4\cdot\sqrt2+9\cdot√(36)\cdot\sqrt2\\\\=17\cdot2\cdot\sqrt2+9\cdot6\cdot\sqrt2=34\sqrt2+54\sqrt2=88\sqrt2\\\\\text{Answer:}\ \ 88\sqrt2\\\\\text{Used:}\ √(a\cdot b)=√(a)\cdot√(b)`

Answer 2

`= > 17 √(8) + 9 √(72) \\ \\ = > 17 * 2 √(2) + 9 * 6 √(2) \\ \\ = > 34 √(2) + 54 √(2) \\ \\ = > 88 √(2) \\ \\ {1}^(st ) option \: 88 √(2) is \: the \: correct \: answer. \:`
