Answer:

a=sqrt[50]; ?=50

Step-by-step explanation:

Using the Pytagorean theorem in the right triangle:

A^2+B^2=C^2, with A=a, B=a, and C=10

Replacing in the formula:

a^2+a^2=10^2

Adding like terms:

2a^2=100

Solving for a: Dividing both sides of the equation by 2:

2a^2/2=100/2

a^2=50

Square root both sides of the equation:

sqrt(a^2)=sqrt(50)

a=sqrt(50)

Solve the equation for the unknown variable.

Georgia [21]

Answer:

d = -3

Step-by-step explanation:

Given the equation:

$d^3 = -27$

Solve for d:

Take both sides cube root we have;

$d =\sqrt[3]{-27}$

We can write 27 as:

$27 = 3 \cdot 3 \cdot 3 = 3^3$

then;

$d = \sqrt[3]{-3^3}$

Using the rules:

$\sqrt[n]{a^n} = a$

$\sqrt[3]{-1} = -1$

then;

$d = -\sqrt[3]{3^3} = -3$

therefore, the unknown variable d is, -3
