log 21^5

5 log 21

5 log (3*7).

using product law

log mn=log m+log n

5 ( log 3 + log 7)

5 (0.4771+0.8451)

5*(1.3222)

10/2(1.3222)

\underline{ \huge\mathfrak{here's \: ur \: solution}}

= log 21⁵ = 5 log 21 = 5 log(7 × 3) = 5( log 7 + log 3)

= 5 (0.8451 + 0.4771) = 5 × 1.3222


\huge \bold{ = 6.6110}
