6 0

Answer:

The greatest value of x is in equation

(2), x=\sqrt{26}\approx5.09

Step-by-step explanation:

<u>Equation (1) :</u>

x^2=17

Take square root of both side

\sqrt{x^2}=\sqrt{17}\\\\(x^2)^{\frac{1}{2}}=\sqrt{17}\\\\x\approx4.12

<u>Equation (2) :</u>

x^2=26

Take square root of both side

\sqrt{x^2}=\sqrt{26}\\\\(x^2)^{\frac{1}{2}}=\sqrt{26}\\\\x\approx5.09

<u>Equation (3) :</u>

x^3=64\\\\x^3=4\times4\times4\\\\x^3=4^3

Take cube root both side

\sqrt[3]{x^3}=\sqrt[3]{4^3}  \\\\(x^3)^{\frac{1}{3}}=(4^3)^{\frac{1}{3}}\\\\x=4

<u>Equation (4) :</u>

x^3=27\\\\x^3=3\times3\times3\\\\x^3=3^3

Take\ cube\ root\ both\ side\\\\(x^3)^{\frac{1}{3}}=(3^3)^{\frac{1}{3}}\\\\x=3

valkas [14]

Answer:

h=A/b

Step-by-step explanation:

Think of putting number in the place of the letter, for example

A is 4

b is 2

h is 2

4=2 x 2        then plug the numbers in the right spot

2=4/2           then see what can be rearranged or what is left to make the
