djyliett [7]2 years ago
3 0

Answer:

x= 6 ± √31

Step-by-step explanation:

x^2-12x=-5

x^2 -12x +36= -5 +36

(x -6)^2= 31

√(x -6)^2= ±√31

(x-6)= ±√31

x= 6 ± √31

ahrayia [7]

Answer:

let the two number be x and y then,

x+y=12

x-y=-4

-----------

2x=8

or, x = 4 put the value of x in first equation

4+y= 12

or, y=12-4

or, y= 8 hence the two number is 4 and 8

Directions: Raise the powers of all variables and numbers indicated, and then turn the following expressions in radical form int
True [87]

The value of the exponents in simple exponential form is x^{\frac{44}{5}} .

The mathematical operation of exponentiation, written as bⁿ, involves the base number (b) and the exponent (or power) number (n). The way to say this word is "b (elevated) to the (power of) n."

  • Exponentiation corresponds to repeated base multiplication when n is a positive integer since bⁿ is the outcome of multiplying n bases. The exponent is often displayed to the right of the base as a subscript.
  • The phrase "b to the nth power" or simply "b to the nth" is used to refer to bn. Other variations are "b (raised) to the power of n," "the nth power of b,"  and "b to the power of n" and "b to the nth power,"

The properties of exponents tell us that when the bases are equal then on multiplication the powers are added and on division the powers are subtracted.

\sqrt[5]{5^y} \cdot(5^4)^3 = 5^{\frac{y+60}{5} }

\sqrt[5]{5^x} \cdot(5^4)^3 = 5^{\frac{x+60}{5} }

Therefore the properties of exponents can be used to find the exponential solutions.

Can someone please solve this problem
ruslelena [56]

ANSWER

\boxed { \sqrt{} }30 \degree

\boxed { \sqrt{} }210 \degree

EXPLANATION

We want to solve

\cot( \theta)  =  \sqrt{3}

where

0 \degree \:  \leqslant x \leqslant 360 \degree

We reciprocate both sides of this trigonometric equation to obtain:

\tan( \theta)  =  \frac{1}{ \sqrt{3} }

We take arctangent of both sides to get;

\theta =  \tan ^{ - 1} ( \frac{1}{ \sqrt{3} } )

\theta = 30 \degree

This is the principal solution.

The tangent ratio is also positive in the third quadrant.

The solution in the third quadrant is

180 +  \theta = 180 + 30 = 210 \degree
