Write the following numbers as the power of base 0.5
(0.25)^8 and (0.125)^4
Lesson 5: Find the value of a so that (a: 0.1) + (a : 0.2) + ( a : 0.5) + ( a : 0.25 ) + ( a : 0.125) = 290
\(a:0,1+a:0,2+a:0,5+a:0,25+a:0,125=290\)
\(a\times10+a\times5+a\times2+a\times4+a\times8=290\)
\(a\times\left(10+5+2+4+8\right)=290\)
\(a\times29=290\)
\(a=\dfrac{290}{29}\)
\(a=10\)

Answer:
2*4*8*0.5*0.125*0.25*(0.4321+0.5679)
1/2:0.5-1/4:0.25+1/8:0.125-1/10:0.1
1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0.1
1/2 : 0.5 - 1/4 : 0.25 + 1/8 : 0.125 - 1/10 : 0. 1
= 1 - 1 + 1 - 1
= 0 + 0
= 0
\(\frac{1}{2}:0,5-\frac{1}{4}:0,25+\frac{1}{8}:0,125-\frac{1}{10}:0,1\)
\(=\frac{1}{2}:\frac{1}{2}-\frac{1}{4}:\frac{1}{4}+\frac{1}{8}:\frac{1}{8}-\frac{1}{10}:\frac{1}{10}\)
\(=1-1+1-1=0\)
1/2:0.5-1/4:0.25+1/8:0.125-1/10:0.1
1/2:0.5-1/4:0.25+1/8:0.125-1/10:0.1
1/2:0,5-1/4:0,25+1/8:0,125-1/10:0,1
=1-1+1-1
=0
