Simplify |
\$ sqrt(12) + sqrt(4) + sqrt(8) \$ |
2 |
'\$ 12 \$' can be written as the product of |
\$ 4\times3 \$ |
3 |
'\$ 8 \$' can be written as the product of |
\$ 4\times2 \$ |
4 |
After Substitution |
\$ sqrt(4\times3) + sqrt(4) + sqrt(4\times2) \$ |
5 |
'\$4\$' is a perfect square of '\$2\$' |
\$ 2sqrt(3) + 2 + 2sqrt(2) \$ |
6 |
Answer |
D = \$ 2sqrt(3) + 2 + 2sqrt(2) \$ |
