a) -5√9 + 2√169 = ?
b) 10³√2 + 4³√2 - ³√2

Answer 1

a) -5√9 + 2√169 =

-5(3)+2(13)=-15+26= 11

b) 10³√2 + 4³√2 - ³√2

(10+4-1) ³√2 = 13 ³√2

Answer 2

a)

$\mathsf{-5\sqrt{9}+2\sqrt{169}=-5.3+2.13=-15+26}$

$\boxed{\boxed{\mathsf{-5\sqrt{9}+2\sqrt{169}=11}}}$

b)

$\mathsf{10\sqrt[3]{2}+4\sqrt[3]{2}-\sqrt[3]{2}}$

$\boxed{\boxed{\mathsf{13\sqrt[3]{2}}}}$
