I can
OpenStudy (anonymous):
ok it has tpo do with integrals
OpenStudy (anonymous):
ok
OpenStudy (anonymous):
\[\int\limits\limits_{1}^{7} 1/\sqrt[3]{t} dt\]
OpenStudy (anonymous):
if \[f(x)=1/\sqrt[3]{t}\]
\[F(x)=(3/2)\sqrt[3]{t}^2\]
The result is F(7) - F(1)
Calculate that for yourself

find the value of b?
OpenStudy (jit4won):
\[\int\limits_{3}^{b}\]\[\int\limits_{}^{}3x ^{2}dx = 3x^{3}/3 = x^3\]
OpenStudy (jit4won):
substituting the limits
we get
\[b^3 - 3 ^3 \]
OpenStudy (jit4won):
now \[b^3 - 3^3 = 37 \]
OpenStudy (jit4won):
\[b^3 =27+37\]

\[b^3=64 \]
OpenStudy (jit4won):
\[ b^3 = 4^3 \]
OpenStudy (anonymous):
so what happen to the 37?
OpenStudy (jit4won):
b=4 is your answer
OpenStudy (jit4won):
