√841 x 15 pangkat 2 = n+475, nilai n adalah

Penyelesaian :

√841 x 15² = n + 475

√ 841 x ( 15 x 15 ) = n + 475
√ 841 x 225 = n + 475
√ 189.225 = n + 475

Nilai n
= 189.225 - 475
= 188.750

Atau
Nilai n
= 435 - 475
= ( - 40 )

√841×15^2 = n+475
√841×(15×15) = n+475
√841×225 = n+475
435 = n+475
435-475 = n
-40 = n
