4a.4²x +3=1

Slotuion:

4²x + 3=1 : <em>x</em>= -⅛ (Decimal:<em>x</em>= -0.125)

Steps

4² x +3=1

4²=16

16x + 3=1

Subract 3 from borh sides

16x +3-3=1-3

Simplify

16x=-2

Divides both sides by 16

\frac{16 \times }{16} = [tex] \frac{ - 2}{16}

[/tex]

Simplitfy

\frac{16 \times }{16} :  x

Simplify

\frac{ - 2}{16}: -⅛

<em>x</em> = -⅛

therefore the answer is <em>x</em><em>=</em><em> </em><em>-</em><em>⅛</em>

4b.ex-1 -5 =5

x~=3.30258

explanation:

e^(x-1)=10

x-1=ln 10

x-1~=2.30258

x~=3.30258

You have writing errors may be

\\ \rm\Rrightarrow 4x²+3=1

\\ \rm\Rrightarrow 4x²=1-3

\\ \rm\Rrightarrow 4x²=-2

\\ \rm\Rrightarrow x^2=-1/2

\\ \rm\Rrightarrow logx²=-log0.5

\\ \rm\Rrightarrow 2logx=-log0.5

\\ \rm\Rrightarrow logx=0.15

\\ \rm\Rrightarrow x=10^{0.15}

\\ \rm\Rrightarrow x=1.412

#2

\\ \rm\Rrightarrow e^{x-1}-5=5

\\ \rm\Rrightarrow e^{x-1}=10

\\ \rm\Rrightarrow x-1=ln10

\\ \rm\Rrightarrow x-1=2.3

\\ \rm\Rrightarrow x=2.3+1

\\ \rm\Rrightarrow x=3.3
