Step-by-step explanation:

<u>Given</u>: √{32⁰ + (2/3)} = (0.6)²⁻³ˣ

<u>Asked</u>: Find the value of x = ?

<u>Solution:</u> Given that √{32⁰ + (2/3)} = (0.6)²⁻³ˣ

⇛√{1 + (2/3)} = (0.6)²⁻³ˣ

⇛√{(1/1) + (2/3) = (0.6)²⁻³ˣ

⇛√{(1*3 + 2*1)/3} = (0.6)²⁻³ˣ

⇛√{(3 + 2)/3} = (0.6)²⁻³ˣ

⇛√(5/3) = (0.6)²⁻³ˣ

Squaring on both sides then

⇛{√(5/3)}² = {(0.6)²⁻³ˣ}²

⇛√(5²/3²) = {0.6}(²⁻³ˣ)²

⇛√{(5*5)/(3*3)} = {0.6}(²⁻³ˣ)²

⇛5/3 = {0.6}(²⁻³ˣ)²

[\mathsf{\because} (aᵐ)ⁿ = aᵐⁿ]

⇛5/3 = (0.6)²*²⁻³ˣ*²

⇛5/3 = (0.6)⁴⁻⁶ˣ

⇛5/3 = (6/10)⁴⁻⁶ˣ

⇛5/3 = {(6÷2)/(10÷2)})⁴⁻⁶ˣ

⇛5/3 = (3/5)⁴⁻⁶ˣ

⇛(3/5))⁻¹ = (3/5)⁴⁻⁶ˣ

[\mathsf{\because} a⁻ⁿ = 1/aⁿ]

Base are the same, so the exponents must be equal.

\mathsf{\therefore} -1 = 4 - 6x

Shift the number 4 from RHS to LHS, changing it's sign.

⇛-1 - 4 = -6x

⇛-5 = -6x

⇛x = {(-5)/(-6)}

\mathsf{\therefore} x = 5/6

<u>Answer</u><u>:</u> Hence, the value of x for the given problem is 5/6.

Solve the system by substitution.
kirill [66]
<h2>Answer:</h2>

x = 1

y = 1

<h3>Step-by-step explanation:</h3>

y=-3x+4\\ y=x

Substitute into one of the equations

-3x+4=x

Rearrange variables to the left sider of the equation

-3x-x=-4

Combine like terms

-4x=-4

Divide both sides of the equation by the coefficient of variable

x=\frac{-4}{-4}

Determine the sign for multiplication or division

x=\frac{4}{4}

Cross out the common factor

x=1

Substitute into one of the equations

y=1

The solution of the system is

\left \{ {{x=1} \atop {y=1}} \right.

<em>I hope this helps you</em>
