Question

Help me and show how you got it please

Answer 1

4)


`\bf √(102)\implies 10.099 \\\\\\ √(121)\implies 11\quad \checkmark \\\\\\ √(125)\implies 11.18 \\\\\\ √(144)\implies 12\quad \checkmark \\\\\\ √(225)\implies 15\quad \checkmark \\\\\\ √(240)\implies 15.49`

5)

check the 1st picture below.

thus


`\bf base\implies \cfrac{1}{4}=x\cdot x\implies \cfrac{1}{4}=x^2\implies \sqrt{\cfrac{1}{4}}=x\implies \cfrac{√(1)}{√(4)}=x \\\\\\ \boxed{\cfrac{1}{2}=x}\qquad \qquad V=x^3\implies V=\left( \cfrac{1}{2} \right)^3\implies V=\cfrac{1^3}{2^3}\implies \boxed{V=\cfrac{1}{8}}`

6)

check the 2nd picture below


`\bf 233=x^2+64\implies 233-64=x^2\implies 169=x^2\implies √(169)=x \\\\\\ \boxed{13=x}\qquad \qquad railing\implies x+x+(x+8)+8+8+\stackrel{\textit{little corner}}{(x-8)}`
