Question

2 log 5 base 3 - 5 log 2 base 3​

Answer 1

Answer:

bar 1.7757

Step-by-step explanation:

2log5(base3)-5log2(base3)=?

=2log (5)/log3–5log (2)/log3.

= [2log 5–5log 2]/log 3.

=[2(log 10/2)-5log 2]/log 3.₩

=[2log 10–2log 2–5log 2]/log3.

=[2log 10–7log 2]/log3.

=[2×1.0000–7×0.3010]/0.4771.

= [2.0000–2.1070]/0.4771.

=-0.1070/0.4771.

=-0.2243.

=-1+(1–0.2243).

=-1+0.7757.

= bar 1.7757
