Make R the subject of the formula if T = \(\frac {KR^2 + M}{3}\)
\(\sqrt\frac{3T - K}{M}\)
\(\sqrt\frac{3T - M}{K}\)
\(\sqrt\frac{3T + K}{M}\)
\(\sqrt\frac{3T - K}{M}\)
ব্যাখ্যা
T = \(\frac{KR^2 + M}{3}\)
3T = KR2 + M
KR2 = 3T - M
R2 = \(\frac{3T - M}{K}\)
R = \(\sqrt\frac{3T - M}{K}\)
3T = KR2 + M
KR2 = 3T - M
R2 = \(\frac{3T - M}{K}\)
R = \(\sqrt\frac{3T - M}{K}\)
