simplify (3b^2)/b

Solution

simplify

\frac{3 b ^{2}}{b}

3 b

Solution steps

\frac{3 b ^{2}}{b}

Apply exponent rule:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{b ^{2}}{b ^{1}} = b^{2 - 1}

= 3 b^{2 - 1}

Subtract the numbers:

2 - 1 = 1

= 3 b^{1}

Apply exponent rule:

a^{1} = a

b^{1} = b

= 3 b

sin (x) - sin (x) cos^{2} (x)

(n^{2} + n) (2 n + 1)

5 U (t - 2) - 3 t U (t - 5)

\frac{4}{3} \cdot 3.14 \cdot 4^{3}

f (x) = \frac{1}{2 x ^{\frac{1}{2}}}
