Work: Calculate the value of equation 3*log(7,2)-log(7,9)+2*log(7,3*sqrt2/4) .
Question type: Mathematical calculation
Solution:
3*log(7,2)-log(7,9)+2*log(7,3*sqrt2/4)
=3*0.356207-log(7,9)+2*log(7,3*sqrt2/4)
=3*0.356207-1.12915+2*log(7,3*sqrt2/4)
=3*0.356207-1.12915+2*0.030265
=1.068621-1.12915+2*0.030265
=1.068621-1.12915+0.06053
=-0.060529+0.06053
=0.000001 Answer:3*log(7,2)-log(7,9)+2*log(7,3*sqrt2/4)=0.000001[4/6 Formula]
Work: Calculate the value of equation (lg8+lg125-lg2-lg5)/(lg(sqrt10)*lg0.1) .
Question type: Mathematical calculation
Solution:
(lg8+lg125-lg2-lg5)/(lg(sqrt10)*lg0.1)
=2/(lg(sqrt10)*lg0.1)
=2/(lg3.162278*lg0.1)
=2/(-0.5)
=-4 Answer:(lg8+lg125-lg2-lg5)/(lg(sqrt10)*lg0.1)=-4[5/6 Formula]
Work: Calculate the value of equation 3^(1+log(3,6))-2^(4+log(2,3))-lg(sqrt5)+sqrt((lg(sqrt2))^2-lg2+1) .
Question type: Mathematical calculation
Solution:
3^(1+log(3,6))-2^(4+log(2,3))-lg(sqrt5)+sqrt((lg(sqrt2))^2-lg2+1)
=3^(1+1.63093)-2^(4+log(2,3))-lg(sqrt5)+sqrt((lg(sqrt2))^2-lg2+1)
=3^2.63093-2^(4+log(2,3))-lg(sqrt5)+sqrt((lg(sqrt2))^2-lg2+1)
=3^2.63093-2^(4+1.584963)-lg(sqrt5)+sqrt((lg(sqrt2))^2-lg2+1)
=3^2.63093-2^5.584963-lg(sqrt5)+sqrt((lg(sqrt2))^2-lg2+1)
=3^2.63093-2^5.584963-lg2.236068+sqrt((lg(sqrt2))^2-lg2+1)
=3^2.63093-2^5.584963-lg2.236068+sqrt((lg1.414214)^2-lg2+1)
=3^2.63093-2^5.584963-lg2.236068+sqrt(0.150515^2-lg2+1)
=3^2.63093-2^5.584963-lg2.236068+sqrt0.721625
=3^2.63093-2^5.584963-0.349485+sqrt0.721625

Work: Calculate the value of equation lg2*lg50+lg5*lg20-lg100*lg5*lg2 .
Question type: Mathematical calculation
Solution:
lg2*lg50+lg5*lg20-lg100*lg5*lg2
=0.30103*lg50+lg5*lg20-lg100*lg5*lg2
=0.30103*1.69897+lg5*lg20-lg100*lg5*lg2
=0.30103*1.69897+0.69897*lg20-lg100*lg5*lg2
=0.30103*1.69897+0.69897*1.30103-lg100*lg5*lg2
=0.30103*1.69897+0.69897*1.30103-2*lg5*lg2
=0.30103*1.69897+0.69897*1.30103-2*0.69897*lg2
=0.30103*1.69897+0.69897*1.30103-2*0.69897*0.30103
=0.511441+0.69897*1.30103-2*0.69897*0.30103
=0.511441+0.909381-2*0.69897*0.30103
=0.511441+0.909381-1.39794*0.30103
=0.511441+0.909381-0.420822
=1.420822-0.420822
