How does finding the square root of a number compare to finding the cube root of a number. Use the number 64 in your explanation

andre [41]

If $x^2=y$ , then $\sqrt[2]{y}=\sqrt[2]{x^2}=x$

if $x^3=y$ , then $\sqrt[3]{y}=\sqrt[3]{x^3}=x$

ok
$64=8^2=4^3$

so
$\sqrt[2]{64}=\sqrt[2]{8^2}=8$
$\sqrt[3]{64}=\sqrt[3]{4^3}=4$

well, the cube root usually bigger

Answer:

Formula for mean in grouped data

= Zfx/ Zf

f = sum of the number of mice

= 35

Frequency = 39 + x

Mean = 7

Fx = 20 + 78 + 112 + 8x + 54

= 264 + 8x

7 = 264 + 8x/ 39 + x

7(39+x) = 264 + 8x

After solving you will get

x = 9

Hope this helps.
