Question

What are the answers for... x^2=121 .... r^3 =216......y^2=64..... and s^3 =125?

Answer 1

${x}^{2} = 121 \\ x = \sqrt{121} = \sqrt{11 \times 11} = 11 or -11 \\ x = 11 or -11 \\ \\ \\ \\ {y}^{2} = 64 = {8}^{2} \\ y = 8,-8 \\ \\ \\ {s}^{3} = 125 \\ {s}^{3} = 5 \times 5 \times 5 = {5}^{3} \\ s = 5$ \\ \\ \\ \\ {r}^{3} = 216 = 6×6×6
= {6}^{3}

r=6

Answer 2

x=11,-11

r=6

y=8,-8

s=5
