Katen [24]

Answer:

Step-by-step explanation:

$(5^{-2}$ × $4^{-4}$ $)^{-2}$

= $(5^{-2}$ $)^{-2}$ x $(4^{-4})^{-2}$ ∴ $(a.b)^{n} =a^{n} .b^{n}$

= $5^{-2.-2}$ x $4^{-4 . -2}$ ∴ $(a^{n} )^{m}$ = $a^{nm}$ // here m is an exponent of $a^{n}$ .

= $5^{4}$ x $4^{8}$

Answer:

$27,182

Step-by-step explanation:

Use the formula Pe^(r * t)

P = principal amount

e = the constant e

r = rate

t = time, in years

10,000 * e ^ (0.05 * 20)

10,000 * e ^ (1)

10,000 * e ≈ 27,182
