Algebra.Com's Answer #442577 by lwsshak3(11628) ![]() You can put this solution on YOUR website! For a particular real number a and base b it is known that log(base b)a=2.75. Determine the value of log(base b)(a^3) \n" ); document.write( "*** \n" ); document.write( "logb(a)=2.75 \n" ); document.write( "a=b^(2.75) (exponential form: base(b) raised to log of number(2.75)=number(a)) \n" ); document.write( "a^3=b^(2.75)^3=b^(8.25) \n" ); document.write( "logb(a^3)=logb(b^8.25)=8.25 \n" ); document.write( "log of base raised to an exponent=exponent \n" ); document.write( " |
