Question

3√176 × 4√2161 ÷(212)2

Answer 1

Step-by-step explanation:

Let x=6.45×981.4.

Taking log on both sides

logx=log(6.45×981.4)

=log6.45+log981.4

=0.8096+2.9919 (using log table)

=3.8015

∴x=antilog(3.8015)=6331.0 (using antilog table)

Ans: 6331

Answer 2

ans.

x= 6.45+981.4

log 6.45+log 191.4

0.8096+2.9919

=3.8015

x=3.8015=63310

=63310

time is a and 63310
