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}](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%20%5Ctimes%20%7D%7B16%7D%20%3D%20%3C%2Fp%3E%3Cp%3E%5Btex%5D%20%5Cfrac%7B%20-%202%7D%7B16%7D%20)

<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)-5=5
e^(x-1)=10
x-1=ln 10
x-1~=2.30258
x~=3.30258

Answer:its 12
Step-by-step explanation:
because there are 36 now and they have 3 times more each year so it is 12 + 12 + 12 = 36
Step-by-step explanation:
14×5=70
8×8=64
(3/70) + (5/64)
= (3×64)+(5×70)
----‐------------------
70×64
= (192+350)/448
=542/448
= 271/224
