simplify (20000)/(4pi(7.510^{-3))^2}

simplify

\frac{20000}{4 π \cdot ( 7.5 \cdot 1 0 ^{- 3} ) ^{2}}

28294212.10522 \dots

Solution steps

\frac{20000}{4 π ( 7.5 \cdot 1 0 ^{- 3} ) ^{2}}

Divide the numbers:

\frac{20000}{4} = 5000

= \frac{5000}{π ( 1 0 ^{- 3} \cdot 7.5 ) ^{2}}

(1 0^{- 3} \cdot 7.5)^{2} = 0.007 5^{2}

= \frac{5000}{0.007 5 ^{2} π}

0.007 5^{2} = 0.00005625

= \frac{5000}{0.00005625 π}

Multiply the numbers:

3.14159 \dots \cdot 0.00005625 = 0.00017 \dots

= \frac{5000}{0.00017 \dots}

Divide the numbers:

\frac{5000}{0.00017 \dots} = 28294212.10522 \dots

= 28294212.10522 \dots

\frac{tan ( x ) + cot ( x )}{cot ( x )}

\frac{x ^{3} - 8 x ^{2}}{x ^{2} - 64}

\frac{25}{24} - \frac{7}{24}

\frac{a}{2} + \frac{a}{2}

\frac{50}{250}
