Answer 1

a)

$\boxed{\boxed{\mathsf{\sqrt{7}={7}^{\frac{1}{2}}}}}$

b)

$\mathsf{4\sqrt{{2}^{3}}={2}^{2}.{2}^{\frac{3}{2}}}\\=\mathsf{{2}^{\frac{7}{2}}}$

c)

$\mathsf{5\sqrt{ {3}^{2}}=\sqrt{{5}^{2}.{3}^{2}}}\\\mathsf{\sqrt{{15}^{2}}={15}^{\frac{2}{2}}}$

d)

$\mathsf{6\sqrt{{a}^{5}}=\sqrt{36{a}^{5}}={(36{a}^{5})}^{\frac{1}{2}}}$
