Question

subtract, need help again! thanks a lot.​

Answer 1

$\quad\qquad\qquad\huge\underline{\boxed{\sf Aηswer☂ }}$

Here's the solution ~

# First

$\qquad \sf  \dashrightarrow \: \sqrt{8} - \sqrt{2}$

$\qquad \sf  \dashrightarrow \: ( \sqrt{2 \times 2 \times 2} )- \sqrt{2}$

$\qquad \sf  \dashrightarrow \: 2\sqrt{ 2} - \sqrt{2}$

$\qquad \sf  \dashrightarrow \: \sqrt{ 2}$

# Second

$\qquad \sf  \dashrightarrow \: \sqrt[3]{24} - \sqrt[3]{3}$

$\qquad \sf  \dashrightarrow \: (\sqrt[3]{2 \times 2 \times 2 \times 3}) - \sqrt[3]{3}$

$\qquad \sf  \dashrightarrow \: 2\sqrt[3]{3} - \sqrt[3]{3}$

$\qquad \sf  \dashrightarrow \: \sqrt[3]{3}$

# Third

$\qquad \sf  \dashrightarrow \: \sqrt[]{125} - \sqrt{45}$

$\qquad \sf  \dashrightarrow \: \sqrt[]{5 \times 5 \times 5} - \sqrt{3 \times 3 \times 5}$

$\qquad \sf  \dashrightarrow \: 5 \: \sqrt[]{5 } - 3\sqrt{ 5}$

$\qquad \sf  \dashrightarrow \: 2 \: \sqrt[]{5 }$

# Fourth

$\qquad \sf  \dashrightarrow \: \: \sqrt[5]{96 } - \sqrt[5]{3}$

$\qquad \sf  \dashrightarrow \: \: \sqrt[5]{2 {}^{5} \times 3} - \sqrt[5]{3}$

$\qquad \sf  \dashrightarrow \: \: 2\sqrt[5]{3} - \sqrt[5]{3}$

$\qquad \sf  \dashrightarrow \: \: \sqrt[5]{3}$

# Fifth

$\qquad \sf  \dashrightarrow \: \: \sqrt[]{75} - \sqrt{27}$

$\qquad \sf  \dashrightarrow \: \: \sqrt[]{3 \times 5 \times 5} - \sqrt{3 \times 3 \times3}$

$\qquad \sf  \dashrightarrow \: 5 \sqrt{3} - 3 \sqrt{3}$

$\qquad \sf  \dashrightarrow \: 2 \sqrt{3}$
