计算:log3^8*log4^27+5^(1-log5^2)+(3又3/8)^(-2/3)+sin(3π/2)计算:log3^8*log4^27+5^(1-log5^2)+(3又3/8)^(-2/3)

计算:log3^8 * log 4 ^27 + 5^(1- log5^2 ) + (3又3/8)^ (-2/3) + sin (3π/2)
计算:log3^8 * log 4 ^27 + 5^(1- log5^2 ) + (3又3/8)^ (-2/3) + sin (3π/2)

计算:log3^8 * log 4 ^27 + 5^(1- log5^2 ) + (3又3/8)^ (-2/3) + sin (3π/2)
log3^8 * log 4 ^27 + 5^(1- log5^2 ) + (3又3/8)^ (-2/3) + sin (3π/2)
=(lg8/lg3)*(lg27/lg4) + 5*5^(-log5^2) + (27/8)^(-2/3) -1
=(3lg2/lg3)* 3lg3/(2lg2) +5*5^[log5^(1/2)] + (3/2)^(-2) -1
=9/2 + 5*(1/2) + (2/3)² - 1
=9/2 + 5/2 + 4/9 -1
=6又4/9
