Question

plzzz solve this........​

Answer 1

Here's the Solutions :

(1)

(1/2)log25 + log10 - (1/3)log8

= 1/2×log5² + log(2×5) - (1/3)log2³

= 2/2log5 +log2+ log5 -(3/3)log2

= log5 +log5+ log2 - log2

= 2log5

= 2×0.69897

= 1.39794

(2)

3log2 - (1/3)log8 + 2log5

= 3log2 -(1/3)log2³ + 2log5

= 3log2 - 3/3log2 + 2log5

= 3log2 - log2 + 2log5

= 2log2 + 2log5

=2(log2 + log5)

=2(0.30103 + 0.69897)

=2×1

= 2

(3)

2log3 + 5log2 -log5 -2log4

=2log3 +5log2 - log5 -2log2²

= 2log3 + 5log2 - log5 -4log2

=2log3 +log2 -log5

= 2×47712 +0.30103 -0.69897

=0.95424+030103-0.69897

=0.5563

(4) and (5) are reffered to the attachment ✔️✔️
