Oblicz ola: Oblicz: log 4*log 2500+log² 25

yht: log4 * log2500 + log²25 = log4 * log(100*25) + (log25)² = = log4 * (log100+log25) + (log25)² = log4 * (2+log25) + (log25)² = = 2log4 + log4*log25 + (log25)² = 2log4 + log25*(log4+log25) = 2log4 + log25*log(4*25) = = 2log4 + log25*log100 = 2log4 + 2log25 = 2(log4 + log25) = 2*log100 = 4

Eta:

	10 000
log2500= log		= 4−log4
	4

to W=log²25+log4(4−log4)= log²25−log²4+4log4=(log25+log4)(log25−log4)+4log4= = 2(log25−log4)+4log4= 2log25+2log4= 2*log100=2*2=4
