Simplify the following expressions:$(3+\sqrt3)(5-\sqrt2)$
Given:
$(3+\sqrt3)(5-\sqrt2)$
To do:
We have to simplify the given expression.
Solution:
We know that,
$(a^{m})^{n}=a^{m n}$
$a^{m} \times a^{n}=a^{m+n}$
$a^{m} \div a^{n}=a^{m-n}$
$\sqrt[n]{a} \times \sqrt[n]{b}=\sqrt[n]{a \times b}$
$\sqrt[n]{a} \div \sqrt[n]{b}=\sqrt[n]{\frac{a}{b}}$
$a^{0}=1$
Therefore,
$(3+\sqrt{3})(5-\sqrt{2})=3 \times 5-3 \sqrt{2}+5 \sqrt{3}-\sqrt{3} \times \sqrt{2}$
$=15-3 \sqrt{2}+5 \sqrt{3}-\sqrt{6}$
Hence, $(3+\sqrt{3})(5-\sqrt{2})=15-3 \sqrt{2}+5 \sqrt{3}-\sqrt{6}$.
